America’s heart may be with the victims of Monday’s horrific Boston Marathon bombings, where at least three people have been killed and more than 100 injured, but the United States Senate is still moving ahead on two highly controversial gun and immigration bills.

On immigration, the Gang of Ocho had planned a press conference today to promote their legislation which would give citizenship to many of the 11 million immigrants currently in the United States illegally and thousands more who have already been deported. After the bombings, those senators announced they would cancel their press conference, but confirmed they will still formally file their bill, called the “Border Security, Economic Opportunity, and Immigration Modernization Act of 2013,” tonight. The Senate Judiciary Committee also confirmed they will go ahead with their previously scheduled hearing on the bill this Friday. A second hearing is scheduled for Monday, and the Senate Democrats still plan for a full Judiciary Committee vote in May.

On gun control, Sens. Joe Manchin, D-W.V., and Pat Toomey, R-Pa., confirmed that they are having trouble rounding up the 60 votes needed to end debate on their “Public Safety & Second Amendment Rights Protection Act.” So far only three Republicans – Sens. Susan Collins, R-Maine; Mark Kirk, R-Ill.; and John McCain, R-Arizona – have committed with Toomey to voting for the bill. If Democrats get all 55 members of their operating caucus to vote for the bill, they still would need one more Republican to cave. But a slew of red state Democrats are still uncommitted, including Sens. Mark Begich, D-Alaska; Mark Pryor, D-Ark.; Max Baucus, D-Mont.; Heidi Heitkamp, D-N.D.; Joe Donnelly, D-Ind.; and Mary Landrieu, D-La. If Democrats lose any one of these senators, the legislation will almost certainly fail. Since they do not have the votes yet, Senate Democratic leadership now says they may push the vote on final passage to Thursday or possibly even next week.
