Here’s Walter Stahr at the 2022 Lincoln Forum giving an excellent presentation on Salmon P. Chase.
The video’s description reads, “Author Walter Stahr discussed Salmon Chase, President Lincoln’s Secretary of the Treasury and his rival for the Republican Presidential nomination in 1860. The Lincoln Forum in Gettysburg, Pennsylvania, hosted this event.”
