A nearby fire is now thought to be the cause of the smoke.
DC fire department confirmed that crews "responded to an outside fire in the 100 block of H St SE that has been extinguished. There were no injuries. This accounts for smoke that many have seen."
All of this homeless person’s belongings just went up in flames under the 695 bridge near H and 2nd SE. Extremely unfortunate... @WTOPtraffic @nbcwashington pic.twitter.com/9YAVsOjUqL

The warning comes as the Capitol remains on high alert ahead of the event on Wednesday.
The lockdown comes as US defence officials said they are worried about an insider attack or other threat from service members involved in securing President-elect Joe Biden's inauguration, prompting the FBI to vet all of the 25,000 National Guard troops coming into Washington for the event.
