The House is set to adopt a rule Tuesday night fining lawmakers hundreds of dollars if they refuse to wear a face mask on the floor.

They will face a $500 fine the first time they break the rule, and $2,500 the second time. The money will be deducted from their pay.

A House Democratic aide who shared the plans said the measure will be part of a procedural vote when the chamber reconvenes Tuesday night to consider the resolution calling on Vice President Mike Pence to invoke the 25th Amendment declaring the president unfit to serve.

House Speaker Nancy Pelosi (D-Calif.) put in place a mask mandate for the House floor in June , but it hasnt carried any monetary penalty until this point.
