Several climate activists were arrested Saturday after blockading the entrance to a West Virginia power plant as part of an effort to call attention to Sen. Joe Manchin's ties to the coal industry.

"Manchin has a lot of power nationwide," said one protester, who told Fox News the demonstrators came to "call him out on his-self dealing. He's not doing what the people of West Virginia want and need him to do."

A West Virginia University student activist, Ryley Haught, told Fox News: "Manchin profits 500,000 a year from the trucks that bring in that coal, and at the same time he serves as the chair of the Energy and Natural Resources Committee. This is a huge conflict of interest."

A company Manchin co-founded with his brother paid the West Virginia Democrat nearly $492,000 in 2020, his financial disclosures show. The company, Enersystems Inc., is run by Manchin's son and sells waste coal to the Grant Town Power Plant, The New York Times reported.

Protesters called on Manchin to abandon his support for fossil fuels and embrace green energy legislation.

"He's decided that the U.S. Chamber of Commerce agenda is better than the agenda for the people of West Virginia and the people of the United States," Rev. William Barber told a crowd of protesters.

Marion County sheriffs warned protesters that if they position themselves too close to the Grant Town power plant fencing, they would risk arrest. Within the first 10 minutes of the protest, West Virginia State Police began arresting activists who sat right in front of the fence.

At least a dozen arrests were made throughout the protest.
