Vice President Biden plans to headline a Democratic fundraiser at climate activist Tom Steyer's home
Two sources close to the event planning, including one DNC official, told The Hill that Steyer would be hosting Biden for a Democratic National Committee fundraiser at his San Francisco home on May 28.
Republicans have pitted Steyer as the Democrats' version of the Koch brothers, and have blamed him for Democrats' insistence on what they consider dangerous climate policies.
The billionaire environmentalist has held fundraisers in the last year which both President Obama and Senate Majority Leader Harry Reid (D-Nev.) attended. The latest fundraiser signals Steyer's increasing commitment to the Democratic party.
