Only eleven days after being sworn in as Pennsylvania’s new attorney general, Josh Shapiro has already responded to the current administration’s travel ban, writes Alexander Burns for The New York Times.

Shapiro, the former Chairman of the Montgomery County Board of Commissioners, has joined a number of Democratic attorneys general who are challenging the ban as unconstitutional on behalf of their states.

A day after Trump’s January 27 decree on immigration, he circulated a draft of an opposition statement to his colleagues before appealing to the full group of Democratic attorneys general for their endorsement. The letter was signed by Democratic legal officers from 16 states as well as the District of Columbia.

The statement had the signers pledge to “use all the tools of our offices to fight this unconstitutional order and preserve our nation’s national security and core values.”

The order has since been halted by a federal judge in Seattle and upheld by the United States Court of Appeals for the Ninth Circuit. It is now expected to end up before the Supreme Court.
