Vivek Ramaswamy's political director leaving to join Trump campaign

With the Iowa caucuses less than 50 days away, one of GOP presidential candidate Vivek Ramaswamy's top political advisers is leaving to work for former President Donald Trump's campaign, according to multiple sources familiar with the move.

Brian Swensen, who served as Ramaswamy's national political director since the spring, confirmed to CBS News he is leaving and directed further questions about his future role to the Trump campaign.

"We love Brian," Tricia McLaughlin, Ramaswamy's communications director, told CBS News. "It's a good move for Brian and we're happy for him."
