The Secret Service, which oversees inaugural security, said Thursday that security plans have been in development for more than a year "to anticipate and prepare for all possible contingencies."
President-elect Joe Biden expressed confidence Wednesday.
"I am not concerned about my safety, security, or the inauguration," Biden told reporters just hours after the siege at the Capitol forced Vice President Mike Pence and other top leaders to be whisked away to safety. "I'm not concerned. The American people are going to stand up, stand up now. Enough is enough is enough."
Many at the Capitol riot shared images of themselves online, but federal authorities and Internet sleuths are attempting to identify others. The FBI’s Washington field office has tweeted dozens of images of rioters on Thursday and asked the public to help identify them.
“A new administration will be inaugurated on Jan. 20,” Trump said in a video posted on Twitter late Thursday. “My focus now turns to ensuring a smooth, orderly and seamless transition of power. This moment calls for healing and reconciliation.”
