Republican representative Darrell Issa of California says he will not run for re-election

Issa was first elected to Congress in 2001 to represent a district that was recently reconfigured due to Prop 50

Republican representative Darrell Issa, whose southern California district was reconfigured following the passage of Proposition 50, has decided not to run for re-election.

After a quarter-century in Congress - and before that, a quarter-century in business - it's the right time for a new chapter and new challenges," he said in a statement on Friday, the last day he would have been able to file as a candidate.
