HBO’s Bill Maher blasted CBS White House reporter Major Garrett as a “huge a***ole” after he asked Obama a tough question at the White House during President Obama’s press conference yesterday.

“Major Garrett is a huge asshole,” Maher wrote on Twitter. “If you wanna “strike a nerve” with POTUS, why not just scream the N word? That should get his attention.”

Maher, who has his own share of critics, currently hosts a comedy show on HBO, the same channel getting exclusive access today to the president for a documentary of his visit to a federal prison.

The documentary will be aired in September.
