4 highlights from Trump's interview with Tucker Carlson

Trump vows to 'seal up the border good and tight' as No. 1 priority

As the interview concluded, Carlson asked Trump what his top priority would be if elected to a second term. The 77-year-old said securing the United States-Mexico border would remain his No. 1 focus, just as in his 2016 election campaign. 

"The first thing I would do would be I would seal up the border good and tight except for people that want to come in legally," he said. He also expressed a desire to take "hundreds of thousands of criminals that have been allowed into our country and getting them out and bringing them back to their country."

The former president asserted that many of these people were coming from prisons and mental institutions in their home countries. 

Trump defended his administration's record on the border, asserting that "I had the strongest border in the history of our country, and I built almost 500 miles of wall. ... [and] another 200 that I was going to build." 

"We built it; it was all set to go. All they had to do was install it. It would have taken three weeks," he added.

He claimed the Biden administration wants "open borders," citing his successor's failure to secure the border.
