White House Chief of Staff John Kelly said President Donald Trump is frustrated by how the press covers his administration.

“It is astounding to me how much is misreported,” Kelly said during a press briefing on Thursday. “I will give you the benefit of the doubt that you are operating off of contacts, leaks, whatever you call them.”

However, he said he would offer them one piece of advice: “Develop some better sources.”

He said Trump has also been frustrated by Congress and the slow pace of passing legislation.
