‘Must be stopped!’ Trump attacks ‘Little Adam Schiff’ as Democrats push back against Nunes memo

President Donald Trump on Monday erupted at Rep. Adam Schiff on Twitter and accused him of "illegally" leaking intelligence.

"Little Adam Schiff, who is desperate to run for higher office, is one of the biggest liars and leakers in Washington, right up there with Comey, Warner, Brennan and Clapper!" the president fumed. "Adam leaves closed committee hearings to illegally leak confidential information. Must be stopped!"

It is unclear what prompted Trump's attacks on Schiff Monday, although the president has been live-tweeting his favorite morning show "Fox & Friends" for much of the morning.

Trump attacked Democrats' push for universal health care after watching a segment on the United Kingdom's National Health Service on "Fox & Friends" Monday, and he then specifically thanked the program for giving him positive coverage that he deemed to be "the truth."
