Suffolk Legis. Jon Cooper (D-Lloyd Harbor) will announce at 1:30 p.m. today that he will not challenge Sen. Kirsten Gillibrand, according to people familiar with Cooper's decision.
Cooper, 54, launched an exploratory committee in the spring to prepare for a primary race against Gillibrand, who Gov. David A. Paterson appointed in January to replace Hillary Rodham Clinton.
Cooper, who raised only $50,000 in the third quarter, declined to comment this morning. He said in October that he was shunning fundraisers until he decided
"We shall see," he said. "You'll have to come to the press conference."
Reps. Carolyn McCarthy (D-Mineola), Carolyn Maloney (D-Manhattan) and Peter King (R-Seaford) have each backed off challenging Gillibrand after showing interest.
