Governor Tom Corbett is expected to sign a congressional redistricting bill into law Thursday, less than two weeks after it was made public.

The bill was written after Pennsylvania lost a seat in Congress during the 2010 census report, forcing the state to create a new district map. 

It went through the Senate and House in just over a week. Some Democrats argue the new district lines give Republicans the upper hand.

The governor is not expected to hold a public signing ceremony.
