Congressional negotiators reached a deal Tuesday on US federal spending, budget officials said, which if passed by lawmakers would avoid a disastrous repeat of a government shutdown that paralyzed Washington. Sources say the 2014-2015 budget agreement, brokered by Senate Democrat Patty Murray and House Republican Paul Ryan in weeks of closed-door negotiations, sets the new annual budget caps at about $1 trillion. Details will be unveiled at a 6:00 pm press conference, according to Ryan's office.
