Another week, another series of demonstrations by opponents of President Donald Trump.
Protesters in cities across the country took to the streets on Monday for "Not My President's Day" rallies with a strong anti-Trump message.
Olga Lexell, who was one of about 20 people who helped organize the events in Los Angeles, Chicago, and New York, said they were intended to show Trump there was widespread opposition to his policies and "ridiculous" executive orders.
"A lot of people are angry because he lost the popular vote and is ruling like somebody who won by a landslide," Lexell said.
Historically, protests against new presidents are not unusual, said David Meyer, a sociology professor at the University of California, Irvine...
"What is unusual is the vigor, speed, size, and number of issues that they're challenging Trump on," Meyer said. "To have a sustained (protest), every weekend, every couple of days, and it's a different issue -- I've never seen anything like this before."
