President Donald Trump Friday brushed aside concerns about the House "hoax" impeachment inquiry and his administration's related travails at the hands of Democrats.

"Adam Schiff is a corrupt politician that is not giving us due process," Trump said before heading to Atlanta for various events. He was referring to the California Democrat and House Intelligence Committee chairman. "And despite all that, we're kicking their a**."

"We are winning so big," the president continued. "My polls are the highest they've ever been.

"I'm leading in all of the states, every swing state," Trump claimed, adding that he had posted strong "fund-raising numbers" in the recent federal reporting quarter.

President Trump also told reporters that he would "love to have" acting White House Chief of Staff Mick Mulvaney testify in the impeachment probe, but added that "I don't want to give credibility to a corrupt witch hunt."

Mulvaney's lawyer told investigators he would not comply with a subpoena shortly before his deposition was to begin — and that his client was directed by the White House to not testify.

"I would love to have Mick go up, frankly," the president said. "I think he would do great.

"I would love to have almost every person go up when they know me. What I don't like is when they have these people go up that I don't know."

Trump also said that he objected to the House beginning public hearings on their investigation next week.

"They shouldn’t be having public hearings," he told reporters. "This is a hoax.

"This is just like the Russian witch hunt," he added, referring the Mueller probe. "This is just a continuation."

The president's remarks contrasted sharply from his allies, who have steadily complained about the lack of transparency in the impeachment investigation.

Sen. Lindsey Graham, R-S.C., has sponsored a resolution slamming the probe and calling for due process and other protections for President Trump.
