The DNC and RNC headquarters are located just blocks from the U.S. Capitol building, which was under siege from a pro-Trump mob on Wednesday.

The FBI is offering a $50,000 reward for information that will lead to the arrest and conviction of the person or people responsible for two pipe bombs found in D.C. Wednesday.

Around 1 p.m. Wednesday, while President Donald Trump was still addressing his supporters at the Save America rally near the Ellipse, multiple law enforcement agencies were notified about a pipe bomb with wires at the Republican National Committee officer location at 310 First Street SE. Just 15 minutes later there were reports of a similar pipe bomb outside the Democratic National Committee office at 430 South Capitol Street SE.
