In Today’s Times
- A letter sent to Senator Roger Wicker, a Mississippi Republican, has tested positive for the poison ricin, adding to security concerns around the Capitol after the Boston Marathon bombing, Jonathan Weisman reports. The Senate post offices on Capitol Hill were shut down and will most likely remain closed for the rest of the week.
- A bipartisan group of eight senators introduced immigration legislation on Tuesday, and the story of how the senators struck an agreement is one of intense across-the-aisle bargaining in an age when compromise is hard to reach, Ashley Parker writes. It was built on unlikely friendships, survived near-stalemates and involved an apology in the form of a cheese pizza.
- Senate leaders will vote on as many as nine gun control amendments on Wednesday, and the outcome could determine the fate of a bill inspired by the shootings in Newtown, Conn., Jonathan Weisman and Jennifer Steinhauer report. In the flurry of crucial votes, some include an expansion of gun rights. If that provision prevails, the Democratic-controlled Senate may end up killing its own bill.
