The Defense Department's top lawyer, Jeh Johnson, will speak at Tuesday's event Defense Secretary Panetta released a video marking June as LGBT Pride Month
Washington (CNN) –– Less than a year after the repeal of the law regarding homosexuals serving openly in the U.S. military, the Pentagon will host a Lesbian, Gay, Bisexual and Transgender Pride Month event on Tuesday.

The Defense Department's top lawyer, Jeh Johnson, will be the keynote speaker.

His address will be followed by a panel discussion called "The value of open service and diversity."

Earlier this month, Defense Secretary Leon Panetta released a video marking the month of June as LGBT Pride Month.

In the video, Panetta said, "Going forward, I remain committed to removing as many barriers as possible to make America's military a model of equal opportunity, to ensure all who are qualified can serve in America's military, and to give every man and woman in uniform the opportunity to rise to their highest potential."

(CNN) –– A same-sex ceremony between an enlisted woman and a civilian woman on a U.S. Army post last month drew protests from lawmakers Thursday.

The "private religious ceremony" took place at Fort Polk in Louisiana in May, post spokesman Scott Stearns said, but he would confirm few other details.

Rep. John Fleming, a Louisiana Republican whose congressional district includes the Army post, said the military confirmed to him that the same-sex ceremony was performed by an Army chaplain in the chapel.

The incident was an inevitable consequence of the end of the don't ask, don't tell policy in September, which previously banned [open] homosexuals from military service, Fleming said.

"The liberal social experiment with our military continues," Fleming said. "A same-sex marriage-like ceremony should not have occurred at Fort Polk, especially since the people of Louisiana have made it abundantly clear that our state does not recognize same-sex marriages or civil unions."
