       Vice President Kamala Harris speaks from Statuary Hall at the U.S. Capitol to mark the one year anniversary of the Jan. 6 riot at the Capitol by supporters loyal to then-President Donald Trump, Jan. 6, 2022.

       Capitol Police began investigating the pipe bomb on Jan. 6, 2021 at 1:07 p.m., according to an official Capitol Police timeline of events Politico reports it obtained, and Secret Service evacuated a "protectee" at approximately 1:14 p.m, seven minutes later. Sources confirmed to Politico that Harris was the "protectee" who was referred to in the timeline.

       "On that day I was not only vice president elect, I was also a United States Senator. And I was here at the Capitol that morning, at a classified hearing with fellow members of the Senate Intelligence Committee. Hours later, the gates of the Capitol were breached," Harris said in remarks Thursday morning. "I had left, but my thoughts immediately turned, not only to my colleagues, but to my staff, who had been forced to seek refuge in our office, converting filing cabinets into barricades."

       Both the DNC pipe bomb and another placed outside the Republican National Committee were discovered after the vote counting had started -- at 1p.m.

       It's still a mystery to federal officials who planted them.
