To that end, Steyer said he planned to invest $30 million in NextGen America for grassroots organizing in ten states: Arizona, California, Florida, Iowa, Michigan, Nevada, New Hampshire, Pennsylvania, Virginia and Wisconsin.
"My fight is not just in California, my fight is in removing Donald Trump from office, and from power", Steyer said.
Steyer, a hedge fund manager turned environmental activist, has been the left's biggest political spender for two straight election cycles, but he has failed to see a return on his investment.
"I am willing to do whatever it takes to help save our country", Steyer said.

Many observers predicted that Steyer would run either for governor of California in 2018 or for the U.S. Senate seat now held by Dianne Feinstein (D), but in a Monday interview, Steyer said, "I'm not going to run for anything". Kevin de León Feinstein's only serious Democratic primary challenger right now. He is the founder of NextGen America, a liberal advocacy group.
At his press conference, Steyer specifically called out House Speaker Paul Ryan and House Republican colleagues Barbara Comstock of Virginia and Darrell Issa of California. He'll also pour money into holding vulnerable Democratic Senate seats, and electing Democratic governors.
The mid-term elections will be a "fierce battle for the soul of America", Steyer said. He said Monday that he expects to spend at least another $20 million on the effort.
Steyer spent almost $100 million on organizing efforts during the 2016 campaign, where Republicans won the White House and maintained control of the House and Senate.
When asked if he would support Oprah, Steyer said his focus is on the midterms. "We know that the so-called pundits argue that we have to choose between talking about impeachment and talking about policy".
