By David Shepardson (Reuters) -Police arrested a man hours after the Texas State Capitol and grounds in Austin were evacuated on Saturday ahead of a planned protest after a credible threat to lawmakers, the Texas Department of Public Safety said. A state trooper made the arrest of the man in connection with the threats during a traffic stop in La Grange, Texas and police said there was no additional threat. A protest against President Donald Trump dubbed the "No Kings" event was beginning at the Texas Capitol around 5 p.m. CDT Saturday. Police around the U.S. are on high alert after a gunman posing as a police officer killed a Democratic state lawmaker and her husband in Minnesota in an apparent politically motivated assassination, and wounded a second lawmaker and his spouse, state officials said.
