Democracy activists are calling on the Biden White House to join talks about how the Senate can pass the Freedom to Vote Act this year.

More than one in four senators is invested in the fossil fuel industry as the Senate strips major climate programs from the reconciliation bill.
As he stripped major climate programs, Sen. Joe Manchin received large donations from Enterprise Products, the energy giant where his son-in-law is a senior employee and whose lobbying groups are fighting the reconciliation bill.
Joe Manchin raised $1.6 million in the third quarter, including donations from many fossil fuel industry PACs as he announces he is strongly opposed to the major climate program in the reconciliation bill.

The former senator now works with multiple front groups, including one run by a fossil fuel lobbying firm.
Enersystems, Joe Manchin's family coal company, has contracts with the only power plant in West Virginia that burns coal from reclaimed mine projects.
