The controversial former White House aide Omarosa Manigault Newman says she is ready to testify to Congress “anytime, anyplace” about what she knows regarding President Donald Trump’s campaign as it pertains to Russian collusion.

And in her limitless zeal to go after the duly elected and current sitting president, Manigault Newman says she has even offered to appear as a witness at a potential Senate impeachment trial.

“I have the truth on my side as well as 100 emails and documents and other things,” said Manigault Newman in an interview Wednesday with the Yahoo News podcast “Skullduggery,” Yahoo News reported on Friday.

Asked specifically about being an impeachment witness against the president, she reportedly replied, “I think I’ve made it very clear that I am fully willing and ready to testify, to cooperate, to help advance this investigation.”

Even though she’s sending up flares in trying to get herself involved in any impeachment proceedings, there’s been no interest: Manigault Newman told “Skullduggery” that, so far, none of the congressional committees has reached out to her about any testimony.

While Manigault Newman also insisted she has been “cooperating” with special counsel Robert Mueller’s investigation since this spring, she only hinted at her role on the last page of her new book, “Unhinged: An Insider’s Account of the Trump White House.”

The vengeful former reality star, fired from her White House job in December, was coy about exactly how she has been cooperating with Mueller, said Yahoo News.

“I don’t want to compromise Mueller’s probe,” Manigault Newman told “Skullduggery.”

She also said she wanted to include more details about her participation in the Mueller investigation in her book, but her publisher’s lawyers made her take them out.

But Manigault Newman did discuss Michael Cohen, Trump’s longtime lawyer, who pleaded guilty this week to eight federal felonies, including arranging payments to two women in violation of federal election laws.

Manigault Newman charged that Trump “mocked and belittled” Cohen over the years, giving one example to “Skullduggery.”

“Michael wanted Donald Trump to come to his son’s bar mitzvah,” she said. “And he basically begged the president to come — it would mean so much to his son … And Donald came and in front of the entire group said that ‘the only reason I came is because Michael begged me to be here. He literally begged me.’”

Trump “said this in front of all of Michael’s sons, friends, peers, Michael Cohen’s family,” added Manigault Newman, who was also a guest at the bar mitzvah.

“And he was very demeaning about it … He could have just shown up and said, ‘Yeah, I’m here, OK, let’s go.’ But instead, in front of his family, in front of his friends, peers, in front of his religious community, Donald Trump took a shot at him.”

Manigault Newman said she called Cohen on Wednesday, the day after his court appearance. “Michael Cohen and I are still close,” she told “Skullduggery.” “I talked to him today and I wanted him to know and reassure him that his friends are still his friends. We still have his back.”

Manigault Newman said she was “very upset” about the president’s tweet commenting on Cohen’s skills as a lawyer.

“Why kick a man while he’s down, you know?” she reportedly said. “This man is facing jail time, he has a family, he has a beautiful wife. His daughter was my intern at the White House. I love this family and, you’re right, Michael Cohen was 100 percent loyal to Donald Trump. And so I have to tell you that the way he’s been portrayed is completely inaccurate.”

The controversial ex-aide added, “He would not be paying off porn stars if Donald Trump had not slept with them and had these illicit relationships with them and if Donald Trump had not directed him to pay these women off.”
