WASHINGTON — The violent insurrection at the U.S. Capitol is intensifying scrutiny over security at the upcoming inauguration ceremony for President-elect Joe Biden, which already has been reshaped by the coronavirus pandemic and President Donald Trump’s decision not to attend.

Biden and Vice President-elect Kamala Harris will take the oath of office from the Capitol’s West Front, one of the locations where a mob overpowered police and stormed the building on Wednesday. They also scaled and occupied the scaffolding and bleachers in place for the ceremonies.

Plans for the Jan. 20 inauguration were already scaled back because of the coronavirus. But the brazen attack raises new questions about preparedness for the event that will welcome a new administration after a bitter election.

The congressional leaders responsible for coordinating the inauguration has insisted that events will move forward.

“The outrageous attack on the Capitol, however, will not stop us from affirming to Americans — and the world — that our democracy endures,” said Sens. Roy Blunt, R-Mo., and Amy Klobuchar, D-Minn. “The great American tradition of an inaugural ceremony has occurred in times of peace, in times of turmoil, in times of prosperity, and in times of adversity. We will be swearing in President-elect Biden.”

Security forces have already begun taking extra precautions in the wake of Wednesday’s mayhem. Five people died, including a Capitol Police officer.

Roughly 6,200 members of the National Guard from six states — Virginia, Pennsylvania, New York, New Jersey, Delaware and Maryland — will help support the Capitol Police and other law enforcement in Washington for the next 30 days.

Crews erected tall black metal fences on the Capitol grounds that are designed to be impossible to climb. Similar structures have previously been used around the White House and in other cities that faced prolonged demonstrations.

Such barriers would have gone up anyway in coming days, however, because the inauguration is a National Special Security Event overseen by the Secret Service and scores of other federal agencies, including the Defense Department, which helps lead counterterrorism efforts associated with the event. That’s the same level of security provided during political party conventions or when a dignitary lies in state at the Capitol — but not during a normal congressional session like when rioters breached the building.

“The safety and security of all those participating in the 59th Presidential Inauguration is of the utmost importance,” the Secret Service said in a statement. “For well over a year, the U.S. Secret Service, along with our NSSE partners, has been working tirelessly to anticipate and prepare for all possible contingencies at every level.”
