Cook has personally given $10,800 to Republican candidates and joint fundraising committees and $10,400 to committees on the Democratic side since 2008, according to reports filed to the Federal Election Commission. While he is by no means a large donor, Cook has increased his activity in this election cycle, with about 90 percent of those donations coming since April 2015.
Cook hosted a fundraiser for Republican House Speaker Paul Ryan earlier this year, giving $7,100 to his campaign and a joint committee with the GOP in June. Last year, he gave maximum $2,700 donations to the campaigns of GOP Sen. Rob Portman of Ohio and Democratic Sens. Chuck Schumer of New York and Patrick Leahy of Vermont.
