Fox News contributor and author Dan Bongino responded Monday to top House Democrats Jerrold Nadler and Adam Schiff accusing President Trump of obstructing justice and colluding with Russia.

House Judiciary Committee Chairman Nadler, who would oversee any impeachment proceedings, said Sunday he will send more than 60 document requests to the White House and Justice Department.

"It's very clear that the president obstructed justice," Nadler told ABC News anchor George Stephanopoulos.

Meantime, in a separate interview, House Intelligence Committee Chairman Schiff said he believes there is "direct evidence" of collusion between the Trump campaign and Russians in 2016.

"That is something that we will have to await Bob Mueller's report and the underlying evidence to determine. We will also have to look at the whole body of improper and criminal actions by the president including those campaign finance crimes to determine whether they rise to the level of removal from office," said Schiff.

Bongino said Democrats should learn a lesson from what happened to Republicans in the 1990s when impeachment proceedings were brought against President Bill Clinton and backfired politically.

"We live in a post-fact society now when it comes to the Democrats," he said on "Fox & Friends," accusing Democrats of continuing to "double down" regardless of the lack of evidence.

Bongino scoffed at the notion that there is evidence of collusion.

"Here's why he's doing this now. There's a reason. The Michael Cohen hearing was devastating for them. He was their star witness. ... And what did he do? ... He said the key component of their entire case - that Cohen was in Prague to coordinate whole conspiracy with Russians - Cohen said it wasn't true. He's their star witness, not Trump's and he decimated the entire collusion hoax," he argued.

He agreed that Democrats are now looking past the Mueller probe's conclusions, expecting it to be a "soft landing," and planning for new investigations into financial crimes and other matters.
