Simmons earlier Thursday made a surprise appearance in the press briefing room at the Pentagon, where reports said that he thanked American troops for their service and became emotional discussing his mother’s experience surviving a concentration camp.

The rocker has previously said “people are unhappy” with Trump, but predicted he would be reelected in a “landslide” because of the strong U.S. economy.

Simmons, who was born in Israel, has also praised Trump’s decision to move the U.S. Embassy from Tel Aviv to Jerusalem.
