GREAT FALLS — President Donald Trump is putting pressure on U.S. Immigration & Customs Enforcement to ramp up the number of migrants the federal agency arrests.

President Trump has pledged to carry out the largest deportation program in U.S. history and said it will prioritize detaining violent criminals first.

In Montana, two tribal leaders have offered guidance to members in response to the Trump's order.

Crow Tribe senator Dean Don't Mix from Lodge Grass issued a statement on Monday advising all tribal members to carry tribal and/or state-issued identification at all times.

"View everything you read on social media with a critical eye, determine whether the source of the stories being posted is legitimate, and do your best to spread factual information and positive messages, rather than misinformation and rumors," he said in the statement.

Justin Gray Hawk, Sr., the chairman of Fort Peck Tribes, echoed the advice about ID cards: "I urge all Fort Peck Tribal Members to carry a current Fort Peck Tribal ID."

Gray Hawk noted:

In a letter to the Fort Peck Journal, Gray Hawk noted: "The Fort Peck Tribes and my Administration are closely monitoring this situation. The Indian Citizenship Act of 1924 is an act of Congress and a fundamental right protected by the United States Constitution and cannot be overturned by an executive order."

Don't Mix also said: "None of our Crow tribal members should live in fear of being arrested or deported by federal immigration agents. Social media may be abuzz with scary stories right now, but our longstanding rights to our homeland, and our citizenship, have been consistently recognized and upheld by the United States since it entered into its first Treaty with our tribe, in 1825."

Along with carrying identification, Don't Mix recommends tribal members also "not escalate the situation" if they are stopped and questioned about their citizenship.
