The answer to that question is: Probably not. Reps. Daniel Lipinski, a Democrat from Chicago, and Michael Grimm, a Republican representing Staten Island and a little slice of Brooklyn, announced their new transit-focused Congressional caucus just last week, and this week the House has been in recess.
But according to Lipinski spokesperson Guy Tridgell, there has been interest from other lawmakers, and Lipinski and Grimm will be reaching out to colleagues in the coming weeks to recruit more membership.
Rep. Lipinski is well-known for his support for transit and complete streets. He fought hard against the GOP effort to strip transit out of the Highway Trust Fund in 2012 and has been pushing hard to get more frequent service on the Metra commuter line that runs through his district. Lipinski is also a big believer in federal support for bike and pedestrian projects like Safe Routes to School.
Lipinski is a member of the House Transportation and Infrastructure Committee but doesn't serve on the Highways and Transit Subcommittee, serving instead on both Railroads and Aviation.
Congressional caucuses don't have any formal duties, but Tridgell said the Public Transportation Caucus will be an active one. Aside from engaging on any issue that arises in the House, Tridgell said it will focus on state of good repair for transit systems. Though caucuses don't hold hearings like committees do, Tridgell said the Public Transportation Caucus would gather input from stakeholders, including riders, employers, transit operators, business community.
Rep. Grimm is one of a small handful of Republicans to publicly support transit. He represents the only borough of New York not connected to the city's subway system. By New York standards, Staten Island is fairly car-dependent, but by the standards of most of the country's Republican districts, it's a transit paradise.
