(CNN) A Democratic member of the House Armed Services Committee said he's concerned President Donald Trump will endanger the country by refusing to listen to his top intelligence officials ahead of his second summit with North Korean leader Kim Jong Un.

"God knows what he'll give away," Rep. John Garamendi from California said Monday in an interview with CNN's Wolf Blitzer on "The Situation Room."

Garamendi said he is concerned the President will open formal diplomatic relations with North Korea despite warnings from Director of National Intelligence Dan Coats that North Korea is unlikely to give up its nuclear arsenal.

Last month, Coats and other intelligence chiefs contradicted Trump on national security issues in testimony to Congress. Sources told CNN that the President singled out Coats for criticism the next morning.

Garamendi criticized the President for the conflict with his spy chief, saying that Trump's actions are a national security issue and the President has put the nation in jeopardy.
