Retired Lt. Col. Bob Maginnis, a senior fellow for national security at the Christian conservative group Family Research Council (FRC), is calling for the next president to reinstate “Don't Ask, Don't Tell.”

The military policy that banned gay and bisexual troops from serving openly ended on Tuesday, nearly 18 years after its implementation and 9 months after Congress authorized its repeal. More than 13,000 service members were drummed out of the military for violating the policy.

Miginnis on Thursday told OneNewsNow.com that he would like to see reinstatement of the policy become an issue in the upcoming election cycle.

“They did not tell the Pentagon that homosexuals have to serve; they just said we're removing this law,” Miginnis said. “So, a new president could impose a new regulation, or, for that matter, Congress could pass a law saying, 'We now prohibit the service by people that are known to be homosexual.' That's easily done.”

“Even though it would be the right thing to do, it would take a very courageous future leader to do anything about it,” he added.

In fact, three GOP presidential candidates, former Pennsylvania Senator Rick Santorum, Minnesota Rep. Michele Bachmann, and former Godfather's Pizza CEO Herman Cain, have already vowed to undo DADT repeal, if elected. Cain, however, walked back his comments.
