Robert Strauss, who once headed the Democratic National Committee, served as US trade representative and ambassador to Moscow, and advised presidents from both parties, died in Washington on Wednesday at age 95.
"We can confirm that Robert Strauss passed away peacefully on March 19," the law firm he helped found, Akin Gump Strauss Hauer and Feld, said in a statement.
Strauss, born to Jewish German immigrants, died of natural causes at his home in Washington, the Dallas Morning News reported.
Considered one of Washington's master power brokers, the colorful Texas-born Strauss was known as "Mr. Democrat." But in an era when Washington was less polarized, Strauss easily crossed partisan lines and wielded influence in law, government and politics under a succession of presidential administrations.
"He is absolutely the most amazing politician," former first lady Barbara Bush wrote of Strauss. "He is everybody's friend and, if he chooses, could sell you the paper off your own wall."
