"It's not like further evidence was needed to prove the liberal bias at MSNBC and in the mainstream media, but Chuck Todd's 'hot mic' comments asking if anyone 'checked on' Senator McCain for 'heart palpitations' over General Petraeus' remarks on Iraq show just how quickly the media will try and discredit Senator McCain and anyone who questions President Obama," McCain's communications director, Brian Rogers, said in a statement.

The alleged hot mic incident occurred Thursday before President Obama announced he would send a limited force of 300 advisers in Iraq. According to Mediaite, Todd and Fox News' Ed Henry mocked McCain over Petraeus' Wednesday warning against further intervention in Iraq.
