A massive rally protesting President Donald Trump’s mass deportations and immigration policies blocked traffic on the Hollywood (101) Freeway in downtown Los Angeles Sunday. The protesters gathered Sunday morning on Olvera Street for what the Los Angeles Police Department called a non-permitted demonstration.
