An explosive device was found at the headquarters of the Republican National Committee in Washington and the nearby headquarters of the Democratic National Committee was evacuated after the discovery of a suspicious package on Wednesday, according to three people briefed on the discoveries.
The device that was found at the R.N.C. was a pipe bomb that was successfully destroyed by a bomb squad, according to an official for the R.N.C.
The package at the D.N.C. has yet to be identified, according to a top Democrat briefed on the matter who was not authorized to speak publicly about it.
The R.N.C. and D.N.C. are headquartered just a few blocks away from the U.S. Capitol, which Mr. Trump’s supporters stormed on Wednesday afternoon soon as Congress had gathered to certify President-elect Joseph R. Biden Jr.’s victory and shortly after the president addressed the crowd near the White House.
