*Howard Stern entered the Laura Schlessinger N-word drama this morning – calling her an “a**hole” for the way she handled her racist controversy during a Tuesday appearance on “Larry King Live.”

Dr. Laura appeared on the CNN show to announce that she’ll end her radio program at the end of the year.

“I made the decision not to do radio anymore,” Schlessinger told King. “I want to regain my first amendment rights. I want to be able to say what is on my mind, in my heart, what I think is helpful and useful without somebody getting angry.” [Watch clip below.]

During the “Howard Stern Show” this morning on Sirius/XM, Stern decided to hip Laura to the way first amendment rights actually work. Listen here.

Ironically, Dr. Laura was accused of trying to snatch away Stern’s first amendment rights more than 10 years ago.

As part of a proposed deal to launch a talk show with CBS in 1999, Laura demanded that the studio forbid Stern from insulting her on his radio show, which was owned by CBS at the time.

When CBS refused to muzzle Stern, Dr. Laura backed out of the deal and ran to Paramount.
