(CNN) Rep. Frederica Wilson, D-Florida, said Monday that Hillary Clinton should have fired an adviser on her 2008 campaign when the person was accused of sexual harassment.

Wilson at first asked CNN's Poppy Harlow if she was "sure" that Clinton, a fellow Democrat, was aware of the allegations facing faith adviser Burns Strider. When Harlow explained to Wilson that the 2008 candidate was aware, the congresswoman then said Clinton should have fired Strider "on the spot."

Two sources who worked on the 2008 campaign told CNN last week that Clinton decided not to fire Strider against the recommendation of her campaign manager. A female campaign staffer had accused Strider of harassment that included inappropriate touching, kissing her forehead and sending her suggestive emails, the sources said. The woman shared an office with Strider.

After hearing of the complaint, Clinton campaign manager Patti Solis Doyle and other senior aides urged Clinton to fire Strider, but Clinton declined to dismiss him and kept him on for the rest of her failed run for the Democratic nomination, the sources said.

"Patti wanted him out but she was overruled," one source said.
