A day after it was revealed that NBC paid money to a female staffer in 1999 who accused MSNBC’s Chris Matthews of sexual harassment, the network kept mum Sunday about whether there were other women who had accused the long-time host of inappropriate behavior.

The Daily Caller first reported on the payment Saturday. The website reported that Matthew paid $40,000 to the woman who worked on his show “Hardball with Chris Matthews” as an assistant producer.

Representatives at NBC, CNBC and MSNBC did not respond to Fox News emails and calls Sunday requesting comment on whether other sexual harassment complaints had been filed against Matthews since the payout.

NBC News confirmed Sunday that Matthews was issued a reprimand in 1999 after the woman complained to CNBC executives.
