A clean coal bill could be introduced in the Senate this week as a compromise between the White House and Republican leaders in the House.
The House and the Senate have already come to an agreement on a new version of the bipartisan legislation to combat climate change.
But Senate Republicans are still trying to hammer out differences over how much funding they want to give to the coal industry, including whether they want the legislation to include provisions to expand a carbon tax.
The White House is expected to be on Capitol Hill Thursday afternoon to brief members of Congress on the legislation.
The Senate is expected on Friday to vote on the new clean coal legislation.
