KNOXVILLE (AP) — An antique car collection of the late U.S. Sen. Howard Baker is being auctioned off this weekend to benefit the University of Tennessee center that bears his name.

The six vehicles include a 1941 Lincoln Continental, a 1951 Hudson Hornet and a 1962 Ford Galaxie. They are scheduled to be auctioned at the Howard H. Baker Jr. Center for Public Policy on the UT-Knoxville campus on Saturday.

Baker, who died last year at age 88, was known as "The Great Conciliator" during his time in the Senate for his ability to forge compromises amid bitter partisan differences.

Baker became known for cutting to the core of the 1973 Watergate hearings when he asked of then-President Richard Nixon: "What did the president know and when did he know it?"
