House Republicans accused the Obama administration of withholding information about its initial response to last year's terror attack in Benghazi, Libya, and issued a subpoena on Tuesday seeking additional information.

Rep. Darrell Issa, R-Calif., wrote Secretary of State John Kerry on Tuesday to notify him of the subpoena, which seeks "all documents and communications" among a handful of State Department officials regarding the crafting of the department's public explanation for the Sept. 11, 2012 attack in Benghazi.

The subpoena is another step in Republicans' long journey to unearth more details about the Benghazi response, which they have used to politically ding President Barack Obama and former Secretary of State Hillary Clinton.

Obama has dismissed much of the Benghazi uproar as a politically-motivated fishing expedition, though his administration did disclose 100 pages worth of copies of emails earlier this month documenting how talking points regarding Benghazi were developed in the immediate aftermath of the attack.
