Trump knows 'he's losing to John McCain and can't let it go': CNN political analyst

President Donald Trump is losing the ongoing feud with Sen. John McCain (R-AZ), said CNN political analyst David Chalian, but he simply can't stop fighting against the dead senator.

In a quick exchange Wednesday, Chalian described it almost as a kind of compulsion.

"When President Trump obsesses on something like this it's a clear indication to me, Wolf, that he understands he's on the losing end of this political argument," Chalian explained. "He knew that last August when Sen. John McCain was laid to rest. He had this inexplicable flap over whether or not the flags should be lowered."

Chalian noted that now Trump seems to be trying to take credit for McCain's funeral.

"But it is so clear, this American hero is so under this president's skin," Chalian continued. "He knows he's losing by comparison to John McCain and he can't seem to let it go. He is completely, in the last week, just continuing this attack on a record that is so clearly above and beyond when it comes to service to this country and the president seems incapable of acknowledging it."
