Florida Republican Sens. Marco Rubio and Rick Scott are both pushing for the U.S. to adopt a more aggressive posture toward China in the wake of Russia’s invasion of Ukraine.

Rubio, the top Republican on the Senate Intelligence Committee, framed China as the more potent threat to U.S. interests than Russia in a speech Tuesday morning at the Heritage Foundation, a conservative think tank located just blocks away from the Capitol.

Like Russia, China boasts a nuclear arsenal. But unlike Russia — or even the Soviet Union during the Cold War — Rubio argued that China holds unparalleled economic influence both in the U.S. and internationally, which he said makes the threat far greater.
