Matthews has been accused of making sexist comments in the past.
In 2011, he said Republican Governor Sarah Palin 'could not be hotter as a candidate'.
'There’s something about her. It’s primordial,' the Hardball anchor said.
Did you see her walk? Runway walk. My God is that good. I could watch that runway show
'When she walks and moves, there’s something electric about it. Look at, there‘s something. Other candidates don’t do this. She’s constantly in motion. She looks, obviously, very attractive. She’s doing something that works.'
In 2008, he told MSNBC's Morning Joe that Hillary Clinton had not earned her right to run for president and that she was only in politics because of her husband, former President Bill Clinton.
'I think the Hillary appeal has always been somewhat about her mix of toughness and sympathy for her,' Matthews said.
'Let’s not forget the reason she is a U.S. senator, the reason she is a candidate for President is because her husband messed around. We keep forgetting it.
'She didn’t get there on her merits, because everyone felt, "My God, this woman stood up under humiliation". Right? That’s what happened.'
He later apologized and admitted his words were 'nasty'.
In 2006, Matthews said 'it would be hard for a woman to take on the job of president' because some men do not like listening to them.
'We were watching Hillary Clinton earlier tonight. She was giving a campaign barn burner speech, which is harder to give for a woman. It can grate on some men when they listen to it, fingernails on a blackboard, perhaps.'
He also said Nancy Pelosi said she would struggle to beat President George W. Bush in debates over drug reform and the minimum wage.
'How does she do it without screaming? How does she do it without becoming grating?' Matthews asked.
MSNBC did not comment.
