Republican U.S. Representative Allen West, a favorite of the conservative Tea Party movement, conceded defeat on Tuesday after two weeks of challenges and partial recounts that only widened his Florida congressional opponent's victory in the Nov. 6 election.

"While many questions remain unanswered, today I am announcing that I will take no further action to contest the outcome of this election," said the outspoken West, who had sought re-election to a second term in Congress.
