Democrats have reportedly introduced relatively secret legislation that would require Mexico to pay for the wall.

According to The Daily Caller:

Democratic Rep. Sheila Jackson Lee of Texas introduced legislation forbidding construction of a wall on the U.S.-Mexico border — unless Mexico pays for it.

Lee introduced the Protect American Taxpayers and Secure Border Act into the House on Dec. 19, which would “prohibit taxpayer funds from being used to build a wall between Mexico and the United States,” and further require that any barrier constructed on the southern border “be paid for using funds provided by the Government of Mexico.”

She referred the bill to the House Committee on the Judiciary and the Committee on Homeland Security, and already has four cosponsors: Democratic Reps. Karen Bass of California, Marcia Fudge of Ohio, Joaquin Castro of Texas and Yvette Clarke of New York.

The Texas congresswoman has remained largely silent on the proposed legislation, as have the bill’s other sponsors.

The House has passed legislation including funding for the border wall but the prospect of it passing the Senate remains slim.
