BERKELEY, California/LANSING, Michigan — Supporters of Donald Trump clashed with counter-protesters at a rally in the famously left-leaning city of Berkeley, California, on a day of mostly peaceful gatherings in support of the US president across the country. At a park in Berkeley, across the bay from San Francisco, protesters from both sides struck one another over the head with wooden sticks and Trump supporters fired pepper spray as police in riot gear stood at a distance. Some in the pro-Trump crowd, holding American flags, faced off against black-clad opponents. An elderly Trump supporter was struck in the head and kicked on the ground. Organizers of the so-called Spirit of America rallies in at least 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 after the Republican's inauguration on Jan. 20. "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. White said police did break up fights between the two sides. "We've made a number of arrests, it's one of those things where we monitor the situation and take action as necessary," he said. The violence comes a month after mask-wearing protesters at the University of California, Berkeley, shut down a planned speech by a provocative far-right commentator by lighting fires and smashing windows. On Saturday, smaller skirmishes broke out in other parts of the country. In Minnesota, 400 Trump supporters packed the state capitol rotunda in St. Paul and were met by a smaller group of counter-demonstrators, according to the Star Tribune. Scuffles erupted and six counter-protesters were arrested, the newspaper reported. In Nashville, Tennessee, Trump supporters and counter-protesters cursed at each other and occasionally made physical contact, but state troopers broke up the fighting, according to the city's public radio station. Most rallies appeared to take place without any disruption or violence, like one outside the Michigan State Capitol in Lansing.
