WASHINGTON — House Republicans unveiled a new, stripped-down spending bill Thursday, aiming to prevent a government shutdown this weekend and allow quarreling lawmakers to punt most of their unfinished business into the new year.The bill would keep the government operating through Jan. 19 and permit lawmakers from both parties to head home for the holidays. It would delay battles over the budget, health care and immigration into January, denying Democrats wins that they had hoped to score this year.Failure to pass the temporary spending measure would trigger a government shutdown at midnight Friday, which would amount to a political pratfall just after the GOP scored a major win on a landmark tax bill. With Republicans controlling Washington, they would not have anyone else to blame for a shutdown debacle.And yet President Donald Trump still tried to blame Democrats while winning over the frustrated House GOP factions."House Democrats want a SHUTDOWN for the holidays in order to distract from the very popular, just passed, Tax Cuts.
