A crowd gathered Monday night on the Texas A&M campus to protest President Donald Trump's travel ban.

The demonstration promoted on Facebook began at Rudder Plaza and moved to an area between Evans Library and the Melbern Glasscock building.

The protest was part of a backlash to President Trump’s policy that has blocked all travel to the U.S. from seven predominantly Muslim countries -- Iraq, Iran, Somalia, Sudan, Syria, Yemen and Libya -- for at least 90 days.

The policy, as part of an executive order he signed Friday, also included the suspension of the U.S. refugee program for Syrian nationals for 120 days.

Similar protests have taken place across the country in the last couple of days.

Supporters of the temporary ban have also had protests in large cities.

About a dozen pro-Trump supporters were on hand at Los Angeles International Airport this last weekend voicing their belief that the president’s immigration order is sensible and overdue.

“He’s keeping our country safe and lawful,” said one woman at the protest.

President Trump’s stand on immigration was important in winning support during the 2016 election.

“I think that it’s a great step to creating much needed action in the right direction," said President Trump supporter Vito Glazers. He said it's ironic that so many people are angry with a president who is following through on campaign promises he made.

Meanwhile, President Donald Trump is lashing out at Democrats after the acting attorney general announced she would not defend his controversial immigration order.

Trump in a tweet accuses Democrats of "delaying my cabinet picks for purely political reasons." He says, "They have nothing going but to obstruct. Now have an Obama A.G."

Acting Attorney General Sally Yates, a Democratic appointee, directed Justice Department attorneys Monday not to defend Trump's controversial executive refugee and immigration ban.

Yates said she was not convinced the order was lawful.

Yates' directive is temporary, given that Trump's pick for attorney general will likely move to uphold the president's policy. Sen. Jeff Sessions is awaiting Senate confirmation.
