After making explosive and unsubstantiated accusations about President Obama on Saturday, President Trump went after him again on Sunday after watching a segment on Fox News.

"Who was it that secretly said to Russian President, "Tell Vladimir that after the election I'll have more flexibility?" Trump tweeted, referring to a statement Obama made when he was running for reelection in 2012.

Trump's fondness for Fox News is well known. During the month of February, there were several instances where the president tweeted out or made seemingly outlandish statements that were traced back to Fox News segments.

While Trump has attacked other news channels and publishers, he almost always speaks glowingly of Fox News, often congratulating the network on its ratings and labeling its coverage of him "great." He has said that Fox & Friends is one of his favorite programs, and he has called the hosts "very honorable people," saying "they have the most honest morning show."

Trump also went after the Democratic National Committee Sunday morning, months after reports suggested the DNC did not allow the FBI to examine computer servers that were hacked.
