King also called Trump a “narcissist” after his attacks on San Juan Mayor Carmen Yulín Cruz for her “poor leadership ability” after Hurricane Maria.

"Donald Trump, the master of self-congratulation. His picture should be next to NARCISSIST in the dictionary,” King tweeted.

King's latest comments came just hours after Pence gave a speech at a prayer walk in Las Vegas. Pence said the city came face to face with pure evil last week when a gunman killed 58 people in what has become the deadliest mass shooting in modern American history.
