Benghazi panel grills Clinton aide Huma

Turmoil swirled again around the Republican-controlled Benghazi committee on Friday as it questioned a senior aide to Hillary Clinton, prompting fresh accusations that the panel was created to damage the Democratic front-runner's presidential campaign.

In a six-hour closed door interview, members and staff sought answers from Huma Abedin, for years a close confidante of Clinton. Abedin has served as the former secretary of state's assistant at the time of the 2012 attacks on US diplomatic facilities in Benghazi, Libya that killed four Americans.

Abedin, now campaign vice chairwoman of Clinton's 2016 presidential campaign, said little about the interview.
