The president was addressing reporters before departing for Alamo, Texas, to inspect the border wall.
On the impeachment, Trump said it's "absolutely ridiculous," and that it's "causing tremendous anger ... causing tremendous danger to our country." The president said he wanted "no violence."
House Democrats on Monday formally introduced the article of impeachment against Trump, charging him with "incitement of insurrection."
The House will hold a floor vote later Tuesday on a Democrats-proposed resolution calling on Vice President Mike Pence to invoke the 25th Amendment to remove Trump from office. If Pence doesn't respond within 24 hours, according to the resolution, the Democrats will push the impeachment proceedings ahead.
