Students at schools in Denver left classes Tuesday in protest of the Trump administration's decision to roll back the Deferred Action for Childhood Arrivals program.

Video taken of the protests shows groups of students in several different areas around Denver marching in opposition to the administration's decision to end the program, which was started in June 2012 under former President Obama.

The students were escorted by police.

Attorney General Jeff Sessions announced Tuesday morning the administration will end DACA, which protects those who were brought into the country illegally as children from the threat of deportation and allows them to work in the U.S.

In his announcement, Sessions said DACA will be phased out by March 5, 2018, giving Congress six months to determine how to address those protected by the program, called Dreamers after the bill by the same name that attempted to do something similar to the Obama program.

DACA currently shields roughly 800,000 illegal immigrants between the ages of 15 and 36, and more than 200,000 who benefit from DACA will lose their legal status by the end of the year if Congress doesn't act, the Department of Homeland Security said Tuesday.

In a statement following Sessions' announcement, Trump defended his decision to rescind DACA, saying the issue will be resolved with "heart and compassion."

"Congress now has the opportunity to advance responsible immigration reform that puts American jobs and American safety first," the president said.

"We will resolve the DACA issue with heart and compassion – but through the lawful democratic process – while at the same time ensuring that any immigration reform we adopt provides enduring benefits for the American citizens we were elected to serve."
