Thousands of demonstrators are going to organize protest on January 20 in Washington to disrupt the inauguration of U.S. president-elect Donald Trump, Reuters reported.

Protesters (DisruptJ20 and Black Lives Matter groups) will try to block all 12 check points at the U.S. Capitol, where Trump will take the oath of office, and along the 2.5-mile parade route down Pennsylvania Avenue.

"We want to shut down the inauguration," organizer David Thurston told a news conference. "We want to see a seething rebellion develop in this city and across the country."

The group has three protest permits and "promises other surprises," said spokeswoman Samantha Miller.

All told, 27 protest groups have been granted permits, more than four times the average number for past inaugurations, according to the National Park Service.

The Women's March, on the day after the inauguration, is expected to attract 200,000 people, said the park service, which issues permits.

The inauguration is expected to draw 800,000 spectators, according to officials. That compares with some 1.8 million attending Barack Obama's 2009 inauguration as America's first black president, one of the largest crowds ever to gather in the U.S. capital for such an event.
