Here are some of the stories that will be making news later today:
Congress gets back to business today after a two-week spring recess. The Senate will convene at 2pm ET. Before leaving town, both the House and Senate passed versions of the president's proposed budget. Now lawmakers must work out a final version.
Throughout the day in Colorado, vigils will be held for victims of the Columbine shootings. It was 10 years ago today that 13 people were killed when two students went on a shooting rampage before killing themselves.
At 9am ET, a suit brought by Hurricane Katrina flooding victims will finally go to trial. The four-week trial won't have a jury. A federal court judge will decide whether the Army Corps of Engineers should be held liable for failed levees that caused catastrophic flooding in New Orleans and St. Bernard Parish. Billions of dollars in damages are at stake.
