Speaking to reporters for the first time since last week Deadly riots at the US CapitolMr. Trump declined to answer questions about his resignation.
His remarks came as he left on a trip to the border wall in Texas.
“We don’t want any violence at all,” the president said.
“On the impeachment, this is really the sequel to the biggest witch hunt in political history, it’s ridiculous – it’s absolutely ridiculous.
“Impeachment is causing tremendous anger… and it really is a terrible thing that they are doing,” Mr. Trump said.
“For Nancy Pelosi and Chuck Schumer to continue on this path, I think it causes enormous danger to our country and it causes enormous anger. ”
Before getting on the Marine One helicopter, he repeated: “I don’t want violence”.
America has remained in shock since last Wednesday, when Trump supporters broke into the U.S. Capitol building in Washington and went on a rampage.
Five people have died in the violence, with the president widely accused of triggering the mess by his comments to the crowd earlier in the day.
Efforts to impeach him a second time began on Monday, when Democrats tabled an article in the House of Representatives.
She accuses the president of inciting the insurgency and claims to have made statements which “encouraged and probably resulted” in the riot on Capitol Hill.
Democrats are trying to convince Vice President Mike Pence to use the 25th Amendment to the US Constitution to kick Mr. Trump out as an “unfit” leader.
Mr Pence is believed to be extremely unlikely to agree to the idea, so an impeachment vote could take place on Wednesday and requires a simple majority to pass.
If it is voted, it would go to the Senate for the trial with senators acting as jurors and voting on whether to acquit or convict Mr. Trump.
However, Republicans control the Senate and would not take over the charges until January 19 at the earliest – Mr Trump’s last day before Joe Biden’s inauguration.
