“There are a lot of angry groups protesting and we thought it was important to show our support,” said Peter Boykin, president of Gays for Trump, who helped organize Saturday’s rally in Washington.

In many towns and cities, the rallies did not draw more than a few hundred people. At some, supporters of the president were at risk of being outnumbered by small groups of anti-Trump protesters who gathered to shout against the rallies.

In Berkeley, the total crowd of both supporters and detractors numbered 200 to 300 people, police spokesman Byron White said. Three people were injured in the clash, including one who had teeth knocked out, and police made five arrests.

One Trump supporter who took part in the violence came equipped with a baton, a gas mask and a shield emblazoned with the American flag.
