Lawmakers and campaign consultants say billionaire environmentalist Tom Steyer is causing some anxiety for Democrats ahead of the midterm elections.
Steyer, founder of the green group NextGen Climate Action, has risen to the forefront of political donors after throwing $8 million behind Terry McAullife to clench the Virginia gubernatorial race.
Steyer has signaled he isn't worried about the anxiety.
"If it makes them [Democratic leaders] nervous, tough. That's just tough," Steyer said in an interview. "People who argue for the status quo and say they're sympathetic, and they understand what we're trying to do, but 'now is not the time,' are not helpful," he said.
