Mika Brzezinski, liberal co-host of MSNBC's "Morning Joe," said Tuesday that it was "pathetic" for Democratic presidential candidate Hillary Clinton to charge one of her opponents with sexism.

Over the weekend, Clinton had referred the first Democratic debate two weeks ago, wherein her closest rival, Bernie Sanders, said that "all the shouting in the world" would not solve gun violence.

"I've been told to stop, and I quote, shouting about gun violence," Clinton said at a campaign event on Friday. "Well, first of all, I'm not shouting. It's just when women talk, some people think we're shouting."

On Tuesday, Brzezinski, who has written two books on women empowerment in the workforce, said Clinton was being disingenuous. Watch the video below.



"That wasn't even funny, that's pathetic," Brzezinski said. "I know sexism. Hillary Clinton knows sexism. She should know better than to let her staff make her do that. She needs to do better."

"She needs to get out there and tell everyone to stop writing lines for her, they're bad," Brzezinski continued. "Really bad. And when we talk about sexism, when we talk about women and equal pay and all things things that are important, let's not denigrate it with that stupidity. Let's not. Because we embarrass ourselves. I'm like, cringing."

Clinton is the current front-runner for her party's nomination. During the second debate, she repeatedly drew attention to the historical implications of a woman being elected president, at times suggesting it should be considered as a factor when voters choose a candidate to support in the race.
