"Her policies domestically and internationally haven't worked," Cruz said on ABC's "This Week." "Internationally, the Obama-Clinton foreign policy is a disaster."

The potential 2016 GOP presidential contender said that Clinton -- a presidential contender in her own right -- has "deliberately stonewalled" questions about Benghazi.

"The sad thing with Secretary Clinton is that it seems to be all politics all the time," he said.

Republicans have criticized Clinton and the administration for their handling of the Sept. 11, 2012, attack at a U.S. post in Benghazi in which four Americans were killed. Democrats have criticized conservatives for politicizing the issue.

Cruz also took a not-so-subtle dig at Clinton's 1998 interview with “The Today Show” when she was first lady and defended former President Bill Clinton against infidelity allegations.

In the interview, she criticized a "vast, right-wing conspiracy" aimed at attacking her husband.

"She's more focused on blaming the so-called vast right wing conspiracy than on the terrorists. The truth shouldn't be partisan," Cruz said on Sunday.
