WASHINGTON—Donald Trump used to brag about how few people were being caught trying to cross the U.S. border illegally. He argued that the low numbers – which, naturally, he said were lower than they actually were – showed how well he was doing deterring illegal immigrants, since the low number of apprehensions suggested that few people were trying to cross in the first place.

Then, this year, the number of apprehensions spiked dramatically. So now Trump is making the exact opposite claim. The high numbers, he said at a rally in Missouri on Friday, show how well he is doing with border security.

“We had a record this month, on the border. We took in and arrested more illegals coming across — many of these were not good people — than we've ever done before,” he said.

That was false, too. He has set no arrest records.

The immigration lie was part of a 73-false-claim week. Trump made 20 of them at the Missouri rally, 16 at a rally in Las Vegas the day prior, and 13 in an interview with The Hill.

Trump is now up to 2,717 false claims for the first 612 days of his presidency, an average of 4.4 per day.

If Trump is a serial liar, why call this a list of “false claims,” not lies? Click here for our detailed explanation. The short answer is that we can’t be sure that each and every one was intentional. In some cases, he may have been confused or ignorant. What we know, objectively, is that he was not telling the truth.
