(CNN) -- U.S. Attorney General Michael Mukasey collapsed while giving a speech Thursday at the Federalist Society dinner at the Marriott Wardman Park Hotel in Washington.
While Mukasey, 67, was talking, his speech began to slur and he then became rigid.
Two people grabbed him and laid him on the ground behind the podium, where he was given medical attention before he was rushed to George Washington Medical Center.
A spokesman for the Justice Department said Mukasey was breathing when he was transported to the hospital and was being evaluated in the hospital's emergency room. His condition was not immediately known.
A tape of the speech shows people rushing to the podium after his collapse. One man is heard asking people to please stay in their seats. In the background, a voice is heard saying "bring his feet up."
Outside the hotel, the tape shows numerous police cars rushing to the scene. Minutes later, a fire truck arrives and then an ambulance.
Mukasey, 67, is a retired federal judge appointed to the bench by President Reagan.
Mukasey was nominated to be attorney general by President Bush in September 2007 and was confirmed by the Senate in November 2007.
As a judge, Mukasey ruled that the U.S. government's detention of "dirty bomb" suspect Jose Padilla was constitutional, but that he must be allowed to meet with his attorneys.
During his attorney general confirmation hearings, Mukasey said he would make legal decisions based "on facts and law, not by interests and motives."
Mukasey also said he would resign from office if faced with a presidential order he believed was unconstitutional.
