One year ago today, Donald Trump descended a gilded escalator into a historic presidential campaign.

We called his announcement speech "a rambling bit of political theater" and fact-checked five statements from his remarks. We rated the claims Mostly False, False, False, False and Pants on Fire.

At the time, Trump’s candidacy was seen by many as a publicity stunt. Today he sits as the presumptive GOP nominee.

What hasn’t changed is that Trump continues to make inaccurate statements, and we have spent the past year trying to keep up.

We’ve fact-checked Trump about 160 times. We have rated 76 percent of those statements Mostly False, False or Pants on Fire. (See his entire PolitiFact file, which updates as we post new fact-checks.) As we noted when we awarded Trump our 2015 Lie of the Year award for his portfolio of misstatements, no other politician has as many statements rated so far down the dial. It’s unlike anything we’ve ever seen.

Here are 10 of the most significant falsehoods that Trump has made during the past year.

Pants on Fire: "The Mexican government forces many bad people into our country."

Setting aside the question of whether Mexicans who have come to the United States are "bad" or not, there is no evidence of any Mexican policy that pushes people out of Mexico and into the United States. As has been the case for decades, a combination of economic and family factors accounts for most of the migration from Mexico to the United States.
