Another high-profile candidate is joining the race to succeed retiring New York Rep. Jerrold Nadler.

George Conway, the conservative lawyer turned Donald Trump critic who was married to former White House counselor Kellyanne Conway, filed a statement of candidacy with the Federal Election Commission on Monday, declaring his intention to run for New York’s 12th District, which includes Manhattan’s Upper West and East sides.

“I’m going into the arena. I’ve already put my money where my mouth is, but now it’s time to lay it all on the line,” Conway wrote in a Monday post announcing a new Substack that did not directly reference a congressional campaign.

“We need Democrats to take over Congress — and not just any Democrats, but the most fearless and relentless ones,” he wrote. “The next two years will show us exactly how much lawlessness Republicans will accept. Doing nothing is the same as saying yes.”
