President Donald Trump suggested Monday some of the Democrats questioning Supreme Court nominee Brett Kavanaugh had their own private behavioral issues, saying they were "not angels" and specifically calling out one he had seen in "very bad situations."

Kavanaugh has denied multiple allegations of sexual misconduct, which have not been corroborated by any direct evidence. Under pressure from some crucial Senate Republicans, Trump ordered the FBI last week to conduct a limited investigation into the sexual assault allegation made by Christine Blasey Ford against Kavanaugh.

At a White House press conference, Trump said the treatment of Kavanaugh and his family by media and Democrats was "not describable."

"It's not fair. I think it's fair to do it to me … Long before I got to office, you've been doing it," he said. "I think for me it's like a part of my job description to handle this crap."

He said the process was "so bad for our country" and said the questioning of Kavanaugh by Democrats on Thursday was a "disgrace."

"I watched those senators on the Democrat side, and I thought it was a disgrace, partially because I know them," he said. "I know them too well, and you know what? They are not angels."

Trump later said he had seen one Democratic senator who was "very aggressive" in some "very bad situations," although he wouldn't say whom and didn't get more specific.

While Trump's press conference was called Monday to discuss the trade deal struck Sunday between the U.S., Canada and Mexico, the questioning soon turned to the controversy surrounding Kavanaugh's nomination.

NBC's Peter Alexander later asked Trump to clarify what he meant by "this crap," appearing to wonder if he was referring to allegations of sexual misconduct made against him.

"I think the press has treated me unbelievably unfairly," he said, saying he hoped they would do better once he won the election. "They got worse. They're worse now than ever. They're loco, but that's OK … I used that word because of the fact we made a deal with Mexico."
