Campaign finance records show California venture capitalist Michael Goguen recently gave Greitens $500,000 and Michigan-based commercial real estate company McKinley Associates gave him $200,000.
The contributions add to an already sizeable pot of money Greitens has raised for a potential 2016 campaign. Greitens had more than $1.1 million to spend at the end of June.
Greitens hasn’t formally announced his candidacy but is touring the state speaking with voters.
Greitens is a former Navy SEAL and author who founded a nonprofit group that helps military veterans serve their communities.
A spokesman cited Greitens’ status as a political outsider as part of the reason for his success in raising money.
