We're not bluffing, the Obama administration told Afghanistan on Tuesday in announcing for the first time it has started planning for the possible withdrawal of all U.S. troops by the end of the year if no security agreement is signed. Statements by the White House and Defense Secretary Chuck Hagel showed President Barack Obama's impatience with Afghanistan President Hamid Karzai's refusal to sign the agreement that would keep several thousand American troops in the country after combat operations conclude this year. In a phone call with Karzai on Tuesday to discuss upcoming elections for a new Afghan leader, Obama made clear that time was running out to properly plan for keeping any U.S. forces in the country beyond 2014, the White House said.President Obama calls Afghan leader to discuss security agreementObama orders planning for bringing home all U.S. troops at the end of 2014Afghan President Karzai refuses to sign a deal to keep some troops thereThe White House says an agreement could happen after Karzai leaves office in April

Washington (CNN) -- In a congressional version of hot potato, the Senate on Friday passed a short-term spending plan that would prevent a looming government shutdown and sent it to the House for a weekend showdown between Republican tea party conservatives and their more moderate party leaders. The 54-44 vote on strict party lines came after Senate Democrats pushed through an amendment to restore funding for Obamacare that House Republicans had eliminated in their version of the spending measure, which would prevent the start of a government shutdown on Tuesday. Now House Speaker John Boehner must decide whether to urge his divided Republican caucus to vote with Democrats to pass the Senate plan, or yield again to a hardline conservative wing that demands making continued government funding contingent on undermining Obamacare.NEW: President Obama criticizes Republican tactics on shutdown, debt ceilingThe Senate sends the House a revised spending plan to avoid a shutdownSenate Democrats restore funding for Obamacare opposed by RepublicansHouse Speaker John Boehner faces a showdown with tea party conservatives
