President Donald Trump has promised to drain the swamp in Washington, D.C., but now the swamp is fighting back, Bill O'Reilly said in his Talking Points Memo on Thursday.

O'Reilly explained that the national media despises Trump and such derision shows in their coverage of his administration. He added that some people in the federal government also want to damage the president.

"That's why you are seeing leaks from intelligence agencies and other federal bureaucracies," O'Reilly said. "All presidents have to deal with leaks, but in this political climate, the press gleefully - gleefully - accepts information from anonymous sources and spins it negative against Trump."

He pointed out that the public and press don't know the full story behind former National Security Adviser Michael Flynn's resignation, but that hasn't prevented the media from speculating about the Trump administration's alleged ties to Russia.

"The press has run wild with the stories, and the Trump haters are relishing a witch hunt," O'Reilly said.

He suggested that when then-candidate Trump first said he was going to drain the swamp, he didn't realize how extensive the problem was.

"After eight years of President Obama, there are many people working in the federal government who like the former president and who despise Mr. Trump. Eliminating all of them and stopping leaks will pretty much be impossible," O'Reilly said. "Also, trying to get fairness out of an anti-Trump press will be impossible as well."

"So the Trump administration has its hands full."
