BATON ROUGE, La. (AP) - Republican U.S. Rep. Bill Cassidy is running for the Senate next year, seeking to keep Democratic U.S. Sen. Mary Landrieu from a fourth term.
Cassidy, a Baton Rouge doctor elected to Congress in 2008, will release a video Wednesday announcing his candidacy.
The video was provided to The Associated Press by someone associated with the Cassidy campaign who asked not to be named because the announcement had not been made public.
In the video, Cassidy describes Landrieu as too close politically to President Barack Obama, who remains unpopular in Louisiana.
Cassidy is the first Republican to declare his intention to run for the Senate seat.
