The MSNBC spokesman said that they thoroughly reviewed the situation at the time and that Matthews received a formal reprimand. Based on people who were involved in matter, the network concluded that the comments were inappropriate and juvenile but were not intended to be taken as propositions.
NBC has a history of hiring men with sexual harassment problems. In November, NBC News fired Matt Lauer for sexual harassment claims; several women accused him of sexual harassment and assault, insisting that network executives knew about his behavior. NBC also fired author Mark Halperin in October after 12 women accused him of sexual harassment (including groping) and for failing to report to his boss, senior vice president, Matt Zimmerman, that he had had relationships with women who worked for him.
By the way, Matthews and Lauer have gone out of their way to criticize Donald Trump and Roy Moore, and Republicans in general, for almost everything, including false sexual harassment claims. Finally, these men are being called out for their hypocrisy.
