Michael Lynn Synar (October 17, 1950 – January 9, 1996) was an American Democratic politician who represented Oklahoma's 2nd congressional district in Congress for eight terms.

Synar's campaign pulled off an upset victory as they circulated copies of a Washington D.C. media report that said Risenhoover slept on a "heart-shaped waterbed," which did not play well with the voters back home in Oklahoma.

In the 1986 Supreme Court decision Bowsher v. Synar, the Court struck down the law stating, in part, that the provision granting executive power to Comptroller General Charles Arthur Bowsher, a legislative branch officer, did "violate the Constitution's command that Congress play no direct role in the execution of the laws."

Working with Interior Secretary Bruce Babbitt, Synar tried to rally environmentalists and raise fees, but senators from Western states successfully blocked their proposals.

The Synar Report led to the passage of the Indian Trust Fund Management Reform Act of 1994, and helped to pave the way for the class action lawsuit, Cobell v. Babbitt, initiated in 1996.

In 1994, Synar was narrowly defeated in a Democratic primary runoff election by Virgil Cooper, a retired high school principal.

[citation needed] After Congress, Synar served as the Chairman of the Campaign for America Project and of the National Bankruptcy Review Commission.
