As Israeli Prime Minister Benjamin Netanyahu received a warm welcome from a joint session of Congress on Tuesday, freshman Sen. Rand Paul (R-Ky.) skipped out on the speech, staging what appeared to be a silent protest of America’s foreign aid to Israel.

As the Senate procession across the Capitol began, the tea-party-backed senator quietly walked to his desk, sat down and began shuffling through papers and newspapers.
