Paul Manafort Placed Under House Arrest As Russia Probe Continues

WASHINGTON, DC — President Trump's former campaign chairman, Paul Manafort, has been placed under house arrest after pleading "not guilty" in court Monday on 12 charges, including "conspiracy against the United States." An indictment for the president's former top aide was announced earlier in the day as party of special counsel Robert Mueller's investigation into Russia's meddling in the 2016 election and potential collusion with the Trump campaign.

On the same day, the office of special prosecutor Robert Mueller announced that another former Trump campaign aide admitted to lying to investigators about contacts with Russia as a part of the FBI's probe into the Kremlin's meddling in the 2016 election and potential collusion with the president's associates.

On Twitter Monday, Trump said the crimes Manafort is accused of occurred long before he joined his campaign. "Sorry, but this is years ago, before Paul Manafort was part of the Trump campaign," Trump tweeted. "But why aren't Crooked Hillary & the Dems the focus?????"

"Also," Trump tweeted, "there is NO COLLUSION!"

Despite Trump's claim that Manafort's supposed crimes occurred "years ago," the indictment against Manafort alleges criminal activity through "at least 2016." He is charged with making false statements to investigators after he left Trump's campaign.

Trump did not tweet about the admission of George Papadopoulos, an early foreign policy adviser to Trump's presidential campaign, that he impeded the FBI's investigation and communicated with people tied to Russia.

Manafort, 68, and one of his business associates, Rick Gates, 45, were both put under house arrest after surrendering themselves to the FBI on Monday. A grand jury handed down their indictments Friday.

Manafort appeared confident as he walked in the front door of the FBI offices in Washington, D.C. with his lawyers. Both are expected to appear in court later Monday to face charges brought by Mueller's team. In addition to the conspiracy charges, both are accused of money laundering, making false statements, working as unregistered foreign agents and failing to file necessary reports of foreign bank and financial accounts.

Bail was set at $10 million for Manafort and $5 million for Gates.

Kevin Downing, Manafort's lawyer, gave a press statement following the hearing.

"There is no evidence the Trump Campaign colleduded with the Russian government," he said. "Today you see an indictment brought by the Office of Special Counsel that is using a very novel theory to prosecute Mr. Manafort regarding a FARA [Foreign Agents Registration Act] filing. The United States government has only used that offense six times since 1966 and only result in one conviction."

In a separate matter, Papadopoulos has pleaded guilty to lying to the FBI about a contact with a Russian professor who had ties to the Kremlin, prosecutors said Monday, according to court documents. Papadopoulos told the FBI in January that the conversation took place before he joined Trump's campaign, but in fact, it took place days after, the report said.

According to the case files, Papadopoulos admitted to misleading officials about his communications with a professor who had "substantial connections to Russian government officials." He spoke with the professor about the Russian government supposedly possessing "dirt" on Hillary Clinton; when discussing this with the FBI, he originally said these talks occurred before he joined the Trump campaign. Later, the documents say, he acknowledged that this was false, and he had admitted that the communications occurred while he was working for the president's team.

In a series of emails revealed in June, the president's son Donald Trump Jr. arranged a meeting during the the campaign with a woman described as a Russian government lawyer in order to obtain "dirt" on the Clinton campaign. Manafort, and Trump's son-in-law, Jared Kushner, also attended that meeting.

A Washington Post report previously found that Papadopoulos repeatedly tried to arrange meetings between his superiors in the campaign and Russian officials.

The government said Manafort and Gates funneled more than $75 million through the offshore bank and financial accounts.

Manafort is accused of laundering more than $18 million hidden in offshore accounts in Cyprus, St. Vincent and the Grenadines and the Seychelles to buy properties and services.

"Manafort used his hidden overseas wealth to enjoy a lavish lifestyle in the United States without paying taxes on that income," the indictment reads. During the period covered in the indictment, the government said Manafort spent $273,455 for car payments on four Range Rovers and a Mercedes; $934,350 at an antique rug store in Alexandria, Virginia; and $849,215 and $520,440 at clothing stores in New York and in Beverly Hills, California, respectively. Also according to the indictment, Manafort spent:

• $5,434,793 at a home improvement company in the Hamptons, New York
• $1,319,281 for home automation, lighting, and home entertainment at a company located in Florida
• $655,500 for landscaping services in the Hamptons, New York
• $20,000 for housekeeping in New York

In the 31-page indictment, Gates is accused of transferring more than $3 million from offshore accounts.

Both men are also charged with making false statements. "As part of the scheme, Manafort and Gates repeatedly provided false information to financial bookkeepers, tax accountants and legal counsel, among others," the indictment read.

Manafort and Gates acted as unregistered lobbyists for the government of Ukraine from 2006 to 2015, the indictment said. Any American working as a paid agent of another country's government must fully disclose this work to federal officials and be registered to do so.

The indictment says that until at least 2016, Manafort and Gates were laundering money to help cover up their work for former Ukraine President and pro-Russia strongman Viktor F. Yunakovyc, who was eventually forced to flee to Russia. They are charged with concealing millions of dollars of payments from Ukraine and avoiding taxes on the income.

In total, the documents say that Gates and Manafort funneled around $75 million dollars through their work for Ukraine.

Former National Security Advisor Michael Flynn, another former top Trump aide, has also been reported to have acted as an undisclosed foreign agent. Flynn was not included in the indictment against Manafort and Gates.

On Friday, news reports suggested that indictments had been handed down by a grand jury in connection with Mueller's probe, but didn't identify Manafort and Gates.

Multiple outlets have previously reported that Manafort has been under investigation for money laundering, undisclosed foreign lobbying and tax crimes.

As news of the indictments spread over the weekend, Trump said on Twitter that the "facts are pouring out" about links to Russia by Hillary Clinton's campaign. "DO SOMETHING!" Trump urged in one of the tweets.

Trump and the White House insist there was no collusion between his presidential campaign and Russia. Both have pointed a finger at Clinton and have suggested that the real story of collusion with Russia is the sale of uranium to Moscow when Clinton was secretary of state.

The tweets also referenced that Clinton's presidential campaign helped fund political research into Trump that ultimately produced a dossier of allegations about his ties to Russia. He also pointed to the uranium sale, the tens of thousands of emails from Clinton's time at the State Department that she later deleted from a private email server, and the decision by then-FBI Director Jim Comey to not bring criminal charges against Clinton for possible mishandling of classified information.

"Instead they look at phony Trump/Russia 'collusion,' which doesn't exist. The Dems are using this terrible (and bad for our country) Witch Hunt for evil politics, but the R's are now fighting back like never before," Trump says across several tweets. "There is so much GUILT by Democrats/Clinton, and now the facts are pouring out. DO SOMETHING!"

In a final tweet on the subject, Trump suggests that Russia's re-emergence into the conversation is no accident."All of this 'Russia' talk right when the Republicans are making their big push for historic Tax Cuts & Reform. Is this coincidental? NOT!"

U.S. intelligence agencies have concluded that Russia interfered with the election to benefit Trump, a finding that Trump has not fully accepted. Mueller and Congress are looking into allegations of ties between Trump associates and Russia.

Manafort resigned from the Trump campaign in August of 2016 after the Times reported on documents that tied the then-campaign chairman to a Ukrainian politician with Russian ties. Manafort originally joined the Trump team to help with delegate counting during the primary; he led the campaign after the ouster of the Corey Lewandowski, Trump's first campaign manager.

Mueller was appointed to oversee the investigation into Russian interference in the election and potential collusion with the Trump campaign by Deputy Attorney Rod Rosenstein. However, he has been given wide latitude to pursue any charges that arise from that investigation.
