There will be big protests against President Donald Trump in many parts of the U.S., including a large march in Philadelphia. This is happening while the president is at a military parade in Washington. People are protesting more because of immigration arrests and because soldiers were sent to Los Angeles, where protests have become violent. Police and officials are using curfews, tear gas, and other things to stop the protests. Soldiers are also helping the police in several states, and they say they will not allow violence or breaking the law. These protests are organized by a group called the 50501 Movement. They want to stop what they see as the government's unfair actions. This day of protest is expected to be the biggest one since Trump became president again, with events planned in almost 2000 places across the country.
