The former Florida senator -- who is looking to challenge Bill Nelson in 2012 to return to DC -- is Tweeting this morning about Nelson's loss of a seat on the powerful Armed Services committee.
"Florida's loss of seat on Armed Services is bad for Florida," the Republican tweeted. "Sen. Nelson should not have given it up."
A spokesman for Nelson called LeMieux's tweet "grossly inaccurate," saying Senate Majority Leader Harry Reid asked Nelson to give up his seat on the committee because the Florida senator was already on more than three major committees.
"So the suggestion by George LeMieux that Sen. Nelson gave up something is outlandish and a sign he'd say or do anything for political purposes," said Dan McLaughlin.
With more Republicans elected last fall, there were fewer Democratic committee seats and Democrats had to give up coveted committee seats, including Broward Democrat Debbie Wasserman Schultz, who lost a seat on the appropriations committee.
