Republican Senator Chuck Grassley spoke on the Senate Floor yesterday afternoon. urging Americans to respect the country’s Constitutional system — and its new commander-in-chief. Grassley and Biden served together in the Senate for 28 years. Grassley has held public office since 1959, over the course of a dozen presidencies.

Grassley is no longer third in line to the presidency. For the past two years, Grassley has served as the senate president pro tem, but a Democrat transitioned into that role yesterday. The position is occupied by the longest-serving senator from the party that holds a majority in the Senate.
