President Donald Trump will sign two executive orders Monday aimed at securing the southern border.

The first order “will strengthen and unleash American law enforcement to pursue criminals and protect innocent citizens,” press secretary Karoline Leavitt said in a morning briefing.

The second order will start a crackdown on sanctuary cities, which the White House says obstruct immigration laws.

“The second EO is centered around protecting American communities from criminal aliens, and it will direct the attorney general and secretary of homeland security to publish a list of state and local jurisdictions that obstruct the enforcement of federal immigration laws,” Leavitt continued.
