'More must be done' on security - top U.S. lawmakers

Following a Tuesday briefing by the FBI on last week's deadly violence at the U.S. Capitol, six top House lawmakers said in statement that they are worried about safety in the near future.

The lawmakers, including Judiciary Chair Jerrold Nadler and Intelligence Chair Adam Schiff wrote: "Based on today’s briefing, we have grave concerns about ongoing and violent threats to our democracy. It is clear that more must be done to preempt, penetrate, and prevent deadly and seditious assaults by domestic violent extremists in the days ahead."

A federal law enforcement source said the FBI has warned of armed protests being planned for Washington and all 50 U.S. state capitals ahead of Biden's Jan. 20th inauguration.

The National Guard prepared to send up to 15,000 troops to Washington, and the Secret Service said it would begin its special security arrangements almost a week earlier than originally planned.

According to a person involved with the planning, the Secret Service-led effort to fortify the event will create a more solemn production on the steps of a Capitol building that was the scene of a bloody siege by supporters of outgoing President Donald Trump.

Far fewer people than usual will attend the ceremony, which already had been scaled back due to the COVID-19 pandemic and now also will have a bulked-up security detail, the person involved with planning said.

The presidential inaugural committee and Washington Mayor Muriel Bowser have told Americans not to travel to the inauguration – which typically draws hundreds of thousands of visitors - and said Washington's National Mall would instead be covered with more than 190,000 flags of different sizes to represent the missing crowds.
