He was in Texas last night bemoaning all of the "millions of criminals" the Biden administration wants to let across the borders. He'll say anything to wring donor money out of his fans.

In the E. Jean Carroll testimony that he had to give last week,
Invoking the Fifth won't help Trump this time
Taxpayers should not foot the bill for Trump’s defending himself against the charge that he defamed his accuser.

In response to the journalist E. Jean Carroll’s claim that Donald Trump raped her in the 1990s, the then-president said in January 2019 that “she’s not my type” and that “it never happened.” That denial, of course, suggests that being Trump’s “type” governs whether he would rape that person. Carroll sued Trump for defamation, and he has reached the point where he is out of good options, at least good legal options. The former president has been ordered to sit Wednesday for a deposition (yes, that means under oath) in a defamation case that centers on his denial of Carroll’s allegation. As I’ll explain later, this is one time where pleading the Fifth Amendment won’t help him much.

"The legal questions here are whether Trump, as president, was considered to be an “employee” of the government and whether he was acting within the “scope” of that employment when he said that Carroll is not his type and that he didn’t rape her."
