Organizers of the so-called Spirit of America rallies in atleast 28 the country's 50 states had said they expected smaller turn-outs than the huge crowds of anti-Trump protesters that clogged the streets of Washington and other cities the day afterthe Republican's inauguration on Jan. 20.

Elsewhere, in Washington, the state patrol says four demonstrators were arrested Saturday in the state capital of Olympia at a rally in support of President Donald Trump, KOMO-TV reports. The TV station says about 225 people attended the pro-Trump rally and a group of about 150 people against Trump staged a counter-protest.

Authorities did not say if the people arrested were pro-Trump or anti-Trump. The station reports that the demonstrators are accused of assaulting a police officer. The state patrol tells KOMO that while no troopers were injured during the rally, a sergeant drove himself to the hospital to get checked out after a demonstrator threw an unknown substance at him.

Similar clashes and police crackdowns were also reported elsewhere in the U.S., including Virginia and Pennsylvania.
