Watch: Donald Trump's Immigration Speech In Phoenix, Arizona

UPDATE: Donald Trump, fresh from a difficult trip to Mexico, warned Americans that the upcoming presidential election is their "last chance" to save the country from its immigration policies. In angry tones and often while shouting, Trump renewed his call for a wall separating the United States and Mexico, which he said would pay for its construction.

Donald Trump was scheduled to make a major speech on immigration Wednesday from Phoenix, Arizona, just hours after his meeting with Mexico president Enrique Peña Nieto created another storm of controversy for the GOP nominee.

At a joint press conference Wednesday afternoon following their meeting, Trump said the two discussed his signature border wall but not who would pay for it. Peña Nieto said later in a statement that he told Trump Mexico would not pay for the wall, an assertion the Trump campaign did not deny.

Trump is also expected to clarify, once and for all, his trademark stances on immigration which vaulted him to the GOP nomination and on which he has seemingly waffled in recent days and weeks.

Trump's event in Phoenix is scheduled for 6 p.m. Pacific Time. You can watch a live stream of it as soon as it begins below.

During the primary season, Trump took a hard-line stance on deporting some 11 million immigrants who are in the country illegally. But recently, Trump has proposed a form of amnesty for some immigrants, a policy stance he blasted his Republican primary opponents for having.

Some of Trump's surrogates and closest allies in recent days have also suggested that his signature wall along the United States' southern border — which Trump insists Mexico will pay for — could end up being more of a "virtual" wall.

Besides clearing up to America, three months before the election, what he really believes on immigration, Wednesday's event will also be a chance for Trump to play some defense in a traditionally Republican state where Hillary Clinton has made significant polling gains on him in recent weeks.

Trump holds just a 2-point lead over Clinton in the latest RealClearPolitics average of major state polls. That should be a major red flag for Trump, the GOP nominee in a state that has voted Democrat just once in the past 16 elections.
