Calling the U.S. immigration situation a “pressing humanitarian issue”, Archbishop Charles Chaput of Denver said lawmakers must work to offer a realistic solution to assist the 12 million undocumented workers already residing in the country.

Archbishop Chaput is calling on Catholics to urge their senators to continue pursuing comprehensive immigration reform, begun with immigration bill, S. 1348.

The archbishop issued the call after the Senate pulled the bill from the floor. The action, says the archbishop, once again delays the possibility of providing a solution to the country’s “flawed immigration system.”

“Though S. 1348 is not the end-all solution to our immigration problems, it provides an important first step for each side to work together in resolving the issues,” he said.
