For the second time in the last few months, the Dole Institute of Politics will honor one of Bob Dole’s former U.S. Senate colleagues with a memorial exhibit.

LIke George McGovern, who died in October, U.S. Sen. Daniel Inouye was an across-the-aisle friend of Dole’s, according to a Dole Institute release. Unlike McGovern, he was actually still serving in the Senate when he died. (All three men served in World War II, as well.) Inouye died Monday at age 88.

An exhibit honoring Inouye will be up through Jan. 25 at the institute, and an online tribute featuring a video interview with the senator from Hawaii is also posted on its website.
