After a rocky road through the U.S. House of Representatives, legislation granting the District a voting seat in the lower chamber will get its first hearing before a Senate committee tomorrow — and pretty much everyone and their mother is set to testify.

In a hearing scheduled to start at 10 a.m. before the Senate Committee on Homeland Security and Governmental Affairs, eight witnesses will discuss the legislation that was passed in the House on April 19. A first panel will include testimony by Senator Orrin Hatch (R-Utah), Rep. Tom Davis (R-Va.), Mayor Adrian Fenty and D.C. Del. Eleanor Holmes Norton. A second panel will feature former vice-presidential candidate Jack Kemp; Wade Henderson, president of the Leadership Conference on Civil Rights; Viet Dinh, a professor at the Georgetown University Law Center and former Bush administration official; and Jonathan Turley, a professor at The George Washington University Law School. Legislation sponsor Sen. Joe Lieberman (I-Conn.) will preside over the hearing.

The folks at D.C. Vote have asked that supporters of District voting rights attend the hearing, but if you’re unable to do so, fear not — we’ll be recapping the testimony throughout the day tomorrow.
