Corporations in Iowa are still prohibited from making campaign contributions, despite an attempt by non-profit corporation Iowa Right to Life Committee, Inc. to remove the ban. The Supreme Court of the United States denied review of the Eighth Circuit Court of Appeals case with no comment.

In Iowa Right to Life v. Tooker, plaintiff Iowa Right to Life alleged the ban on corporate contributions is an unconstitutional bar to free speech and equal protection. The Eighth Circuit did not agree, thus upholding the ban.
