Gidwitz has been a mainstay in the Republican party both in the state and nationally. He has donated $1.3 million to state and local Republican candidates since 1994, and he also co-chaired Gov. Bruce Rauner's first run for office.

The businessman spent an additional $700,000 in 2016 to support Trump and candidates for the U.S. House and Senate.

Gidwitz now faces Senate approval for the ambassador post.
