Rep. Lynn Woolsey, who has represented the North Bay in Congress for nearly two decades, is expected to announce her retirement next Monday at her home in Petaluma.
Woolsey, 73, released a statement Monday saying that she will make an unspecified announcement at her home, joined by Rep. Barbara Lee, D-Oakland, friends and family.
An aide said Woolsey's announcement will concern "her future plans."
Sources close to the Petaluma Democrat said Woolsey will announce she is retiring after completing her 10th term in 2012.
In December, Woolsey said she was considering retirement, noting that she will be 75 and will have served 20 years on the Hill by the end of her current term.
Woolsey said then that she would make her decision in June.
She said she was airing her potential retirement well ahead of time to give those vying to succeed her a chance to make their names known to voters.
Assemblyman Jared Huffman, D-San Rafael, and Marin County political activist Norman Solomon have formed campaign organizations with the intention to run if Woolsey retires.
"Lynn has signaled pretty strongly that she will be announcing this is her last term," Huffman said Monday.
Huffman declined to make any further comment, saying "we need to wait and let her make her announcement."
