Critics slammed President Donald Trump on Monday for saying he’s “not so sure” about a basic right guaranteed by the Constitution.

The moment came during an Oval Office appearance as the president spoke about last week’s public killing of conservative activist and podcaster Charlie Kirk.

Trump has blamed “the left” for the deadly shooting, threatened to prosecute left-wing protesters and said he had instructed Attorney General Pam Bondi to look into using racketeering laws against leftist groups.

On Monday, he mentioned a decades-long peace vigil protest he had removed from near the White House earlier this month, bragging that “it was gone the next day” after he found out about it.

Trump also claimed the protester was part of a “violent radical left group.”
