(CNN) The prank call with President Donald Trump by a comedian pretending to be Sen. Bob Menendez has "chilling" implications, Rep. Gerry Connolly said.

"It's a very chilling thing to contemplate" what kinds of "disruptions" other potential phone impersonators could cause, the Virginia Democrat said in an interview with CNN's Wolf Blitzer on "The Situation Room."

Comedian John Melendez, also known as Stuttering John, called Trump on Wednesday posing as Menendez and Trump called him back from on board Air Force One. The two talked about the New Jersey Democrat's acquittal in a corruption case, the upcoming Supreme Court vacancy and the Trump administration's "zero tolerance" undocumented immigration policy.

A White House official told CNN accepting the call was a mistake.
