Mr Trump was responding to a question on his mounting legal woes after his former attorney Michael Cohen said under oath that Mr Trump instructed him to commit a crime by breaking USA campaign finance laws. "Today, he stood up and testified under oath that Donald Trump directed him to commit a crime by making payments to two women for the principal goal of influencing an election". They are Stormy Daniels, who allegedly got $130,000, and former Playboy model Karen McDougal who was paid $150,000.
Other experts have said that Trump could argue that the payments to the women were not a crime because they were made to protect Trump's reputation, not for the objective of influencing the election.
The Democrats' request is "similar to and in accord with the series of private meetings" Goodlatte and Nadler have held with Department officials and special counsel Robert S. Mueller III's team regarding their investigations of Russian interference in the 2016 election and possible ties between the Trump campaign and Russia, they wrote.
Cohen's admission that he spent money on behalf of the Trump campaign outside of the normal channels is damaging for the president's case, according to Jerry Goldfeder, a New York-based elections and campaign-finance lawyer.
Trump also stressed that his reimbursements to Cohen came from his funds and not his campaign.
His replacement, Vice President Gerald Ford, a decent and respected man, helped put the GOP back on course.
"A large number of counts, ten, could not even be decided in the Paul Manafort case", Trump said, adding: "Witch Hunt".
Mr Trump said: "I don't know how you can impeach somebody who has done a great job". Trump added in a tweet that is certain to raise speculation about whether the president might pardon Manafort at some point.
But if Democrats capture the House, then they will be the ones under intolerable pressure from their own media auxiliaries to pursue impeachment.
In June, New York's acting attorney general, Barbara Underwood, filed a lawsuit against the Trump Foundation over alleged illegal conduct and "unlawful political coordination" to benefit personal and business interests.
Confusion over the web address for the page, michaelcohentruthfund.com, led someone to anonymously register a shorter version, michaelcohentruth.com, that redirects to Mr. Trump's re-election campaign website.
Trump also sought to distance himself from Manafort, who was instrumental in the 72-year-old securing the US Republican nomination. Yet they were unable or unwilling to deliver much on his major legislative proposals in his first year in office.
President Donald Trump warned "everybody would be very poor" if he was ever impeached.
"I don't know how you can impeach somebody who's done a great job", Trump said.
Former George W. Bush press secretary Ari Fleischer stressed that the revelations may be sordid but do not meet the constitutional bar of "high crimes and misdemeanors".
