The Biden-Harris administration last week announced a $55.2 million grant for Blue Whale Materials, a little-known electric vehicle battery recycling company advised by a prominent climate activist whose organization is spending tens of millions of dollars to keep Vice President Kamala Harris in the White House.

Carol M. Browner, one of the few officials that Blue Whale Materials identifies on the "team" page of its website, also serves as the chairwoman of the League of Conservation Voters, a powerful environmental nonprofit that regularly advises federal lawmakers. The activist group launched a $55 million advertising campaign last month to support Harris's campaign shortly after endorsing her.
