WASHINGTON (States Newsroom) — Law enforcement agencies in the nation’s capital were closely monitoring security Thursday following a terrorist attack in New Orleans and a vehicle explosion outside the Trump International Hotel in Las Vegas.

The violent incidents took place just ahead of several high-profile events in Washington, D.C., including the swearing-in of the new Congress on Friday, the certification of the Electoral College vote on Monday, former President Jimmy Carter’s funeral next week, and the inauguration of President-elect Donald Trump on Jan. 20.

Matthew Young, assistant special agent in charge at the U.S. Secret Service, said in a statement the agency would “adjust our security plans as needed.”

“While we cannot comment on protective means or methods, what we can say is that we will continue to work with our federal, state, and local law enforcement partners in assessing the ever-changing threat landscape and will adjust our security plans as needed,” Young said. “Our mission is to provide a safe and secure environment for our protectees and all individuals involved in these events.”

The Secret Service has already designated Congress’ certification of the Electoral College, Carter’s funeral at Washington National Cathedral on Jan. 9, and the inauguration as National Special Security Events, which puts the agency in charge of planning and security logistics.

Those special security events are somewhat common for major political events, like the Republican and Democratic national conventions this summer and for presidential inaugurations.

This is, however, the first year the certification of the Electoral College on Monday will hold that designation after a mob attacked the U.S. Capitol during the last certification.

‘An abundance of caution’

The Metropolitan Police Department in Washington, D.C., posted on social media that while “there is no known threat to the District of Columbia, out of an abundance of caution, MPD has heightened its security posture across the city in light of recent events.”

“Whenever an incident occurs in the country, MPD closely monitors the situation, evaluates intelligence, and assesses our security posture,” MPD wrote in the statement. “As the nation’s capital, we maintain a heightened level of security at all times to ensure the safety of our residents, businesses, and visitors.”

The U.S. Capitol Police did not respond to a request for comment but closed off several streets near the building on Thursday after someone drove on a sidewalk a few blocks away.

“Before 10 a.m., our officers spotted a car that had been driving along the sidewalk, near Peace Circle, and into the grassy area near Third Street, NW, & Constitution Avenue,” USCP wrote on social media. “Officers took the man into custody. Please continue to avoid the area while we investigate the car.”

The person was later charged with reckless driving after the USCP bomb squad determined there was no explosive device inside the car.

At least 15 people died and 35 were injured in New Orleans early Wednesday after a man drove a truck onto Bourbon Street in what law enforcement has declared a terrorist attack.

Local and federal law enforcement agencies are also investigating the explosion of a Tesla Cybertruck outside the Trump International Hotel in Las Vegas on Wednesday. Elon Musk, the CEO of Tesla, is a close Trump associate.

Officials say they have not found any link between the two attacks, though they are investigating further.
