Two sources familiar with the situation told The Daily Caller that Matthews paid $40,000 to settle with an assistant producer on his show, "Hardball with Chris Matthews," in 1999 after she accused him of harassment. An MSNBC spokesperson contested that claim to the Caller, saying the company instead paid significantly less as part of a severance package.

The woman complained to CNBC executives about Matthews making inappropriate comments and jokes about her while in the company of others.

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 the matter, the network concluded that the comments were inappropriate and juvenile but were not intended to be taken as propositions.
