State and local leaders across the country are bracing for a tidal wave of aggressive immigration policies and possible mass deportations that President Donald Trump has vowed to enact in the hours and days following his inauguration Monday.

President Donald Trump issued a series of executive orders related to immigration on his first day in office, including declaring a national emergency at the border. He made the actions official during a signing at the Oval Office on Monday.

Trump campaigned largely on the issue of immigration, promising to carry out mass deportations of roughly 11 million illegal immigrants currently in the U.S.

Trump campaigned on border security promises, and he and his allies argue that his electoral win is an endorsement of his upcoming actions on the issue.

President Trump is planning to invoke muscular presidential powers to begin a sweeping crackdown on immigration.

The president’s Day 1 actions included directives that fly in the face of legal limits on involving the military in domestic operations and the constitutional guarantee of birthright citizenship.

The incoming president plans to take at least 10 actions related to the border or immigration, including ramping up deportations and suspending refugee resettlement.

Donald Trump’s immigrant deportation czar wants Americans to inform on their neighbors by calling a new government hotline.

President-elect Donald Trump's incoming administration is reconsidering plans for immigration raids in Chicago next week after details were leaked, Trump's “border czar” Tom Homan told the Washington Post in an interview on Saturday.

If Trump fulfills his campaign promises on immigration, he could disrupt a fragile equilibrium at the southern border and hurt the economy.

The president intends to boost U.S. oil and gas production and lower costs for consumers.
