Lincoln Diaz-Balart will retire at the end of the year, a senior GOP official tells CNN."]Washington (CNN) – Florida Rep. Lincoln Diaz-Balart, a Republican who represented the Miami-area since 1993, will retire at the end of the year, a senior GOP official confirms to CNN.
Diaz-Balart will announce his decision during a noon news conference at the Florida International University's College of Law. The Republican easily won re-election in a district that Sen. John McCain carried by slightly more than 5,000 votes in the 2008 presidential election.
The congressman's office would not confirm his retirement. "All we can say is to be at the press conference today at noon," said Yanik Fenton, a spokeswoman for the congressman.
Diaz-Balart will be the third incumbent House member to announce retirement plans in the past 24 hours. On Wednesday, CNN confirmed that Rep. Diane Watson, D-California, will announce Thursday she has decided to forgo a reelection campaign.
Rep. Vern Ehlers, R-Michigan, stated on Wednesday that he will leave at the conclusion of the 111th Congress.
