US President Donald Trump has said there is "zero" chance of him being forced from office by his government under invocation of the 25th Amendment.
"The 25th amendment is of zero risk to me," Mr Trump said in Alamo, Texas, in reference to pressure by Democrats on Vice President Mike Pence to remove the president through the almost never used constitutional measure.
Mr Trump warned, without further explanation, that the amendment "will come back to haunt Joe Biden and the Biden administration. As the expression goes, be careful what you wish for."
He also called for "peace" and "calm" in the US after denying responsibility for an attack by some of his supporters on the Capitol building in Washington by his supporters last week.
"Now is the time for our nation to heal and it is time for peace and for calm," President Trump said in Alamo.
Earlier, at the White House, he denied responsibility for the storming of the building and warned that his imminent impeachment is causing "tremendous anger."
Mr Trump - who is set to become the first president in US history impeached for a second time - made clear he takes no blame for the 6 January speech in which he urged supporters to march on Congress.
"They've analysed my speech in my words and my final paragraph, my final sentence, and everybody to the tee just thought it was totally appropriate," he said.
He called his scheduled impeachment in the House of Representatives tomorrow a "continuation of the greatest witch hunt in the history of politics."

The president warned that while "you have to always avoid violence," his supporters are furious.
"I've never seen such anger as I've seen right now," he said.
With just eight days left in his one-term administration, Mr Trump finds himself alone, shunned by former supporters, barred by social media, and now facing the unprecedented stain of a second impeachment.
No longer able to use Twitter and Facebook - two platforms integral to his rise to power in 2016 - President Trump is for the first time struggling to shape the news message, a censoring by technology companies that he called a "catastrophic mistake."
His trip to Alamo, Texas, where he claimed success in building a US-Mexican border wall, was his first live public appearance since last week's chaotic events.
This is not the same Alamo as the famous fortress in another part of Texas, but the trip still marks something of a last stand.
Ever since the 3 November election, President Trump has claimed that he, not Mr Biden, was the real winner.

In the Republican party, which has been loyal for four years, even ultra-loyal senior figures such as Senator Lindsey Graham have finally told Mr Trump that he must accept election defeat.
He remains in denial and yet to congratulate Mr Biden or urge his supporters to stand behind the incoming president after he is inaugurated on 20 January - a gesture of political unity considered all but routine after US elections.
According to to the news website Axios, Mr Trump and the top Republican in the House of Representatives, Kevin McCarthy, had a stormy phone conversation today in which the president continued to push his conspiracy theory that he was the true election winner.
Mr McCarthy reportedly interrupted, telling him: "Stop it. It's over. The election is over."
The House of Representatives votes today on a long shot bid to get Vice President Mike Pence and the cabinet to invoke the US Constitution's 25th Amendment, which would declare Mr Trump unfit to perform his duties and install Mr Pence as acting president.
This is unlikely to happen.
Although Mr Pence is reportedly furious about President Trump's behaviour last week, the two met at the White House yesterday for the first time since the Congress attack and had "a good conversation," according to a senior administration official.
In an interview on ABC News, Health Secretary Alex Azar did not dismiss outright the option of removing Trump, saying: "I'm not going to get into or discuss the 25th Amendment here."
Democrats will follow up the 25th Amendment vote with impeachment proceedings in the House tomorrow.
The single charge of "incitement of insurrection" is all but sure to get majority support.
The Republican-controlled Senate, however, is in recess until 19 January and its leadership says there is no way to rush through an impeachment trial before Biden takes over the following day.
This means that President Trump, who was acquitted in the Senate last year after his first impeachment, would not be forced out of office early.
Not even all Democrats are gunning wholeheartedly for a trial, worried that this would overshadow Mr Biden's first days in office.
The new president will already face the challenges of an out-of-control Covid-19 pandemic, the stumbling vaccination programme, a shaky economy, and the aftermath of violent political opposition from parts of Mr Trump's huge voter base.
