"I think that maybe it should mean 'Ready for Testimony,'" Paul, himself a likely 2016 presidential contender, said Wednesday on Glenn Beck's radio show about the slogan being pushed by the Ready for Hillary Super-PAC.

Paul made his comments as the first House select committee hearing on the 2012 attack on the U.S. diplomatic compound in Benghazi, Libya, got underway.

"To those who believe it is time to move on, that there is nothing left to discover, that all questions have been asked and answered, that we have learned the lessons to be learned — we have heard that before," Committee Chairman Trey Gowdy (R-S.C.) said in his opening remarks.

"And yet the attacks and the tragedies keep coming," he said.

Paul has repeatedly pushed for the former secretary of State to testify on the attack that left four Americans dead, including Ambassador Christopher Stevens, given questions raised since Clinton first testified early last year.

"There's still a lot of questions," he said Monday on Fox News after Clinton's high-profile trip to the Hawkeye State over the weekend to attend retiring Sen. Tom Harkin's (D-Iowa) final steak fry.

"It's funny, now reports have been coming out for about a year saying that she was the biggest and most eager to get arms out of Libya to send them into Syria," Paul said.

On Wednesday, Paul added that in general there needs to be a discussion on whether the Middle East is "more or less safe" than before the Libyan, Syrian and original Iraq wars.

"We'd love to hear from John Kerry on Benghazi, as well," he said.
