Top Clinton Aide Arrives on Capitol Hill Before Benghazi Committee Hearing

Longtime Hillary Clinton aide Huma Abedin appeared on Capitol Hill on Friday to testify before the House Select Benghazi Committee investigating the 2012 attack that killed four Americans.

Abedin, who worked with Clinton at the State Department and is now vice chairwoman of her presidential campaign, is meeting with investigators behind closed doors.

Clinton and her allies said the investigation is politically motivated after House Majority Leader Kevin McCarthy linked Clinton's dropping poll numbers to the committee's work.

"It is a partisan vehicle, as admitted by the House Republican majority leader, Mr. McCarthy, to drive down my poll numbers," Clinton said during the first Democratic presidential debate on Tuesday.

Clinton spokesman Nick Merrill said it is unclear why the committee has asked Abedin to testify "given her lack of knowledge about the events surrounding Benghazi."

Republicans contend that a number of publicly released emails between Abedin and Clinton about Benghazi, along with her role as the deputy chief of staff at the State Department during the September 2012 attacks, more than justify her testimony.

Clinton will testify before the panel next Thursday in a public hearing.
