WASHINGTON (Reuters) -A Republican spending bill backed by President-elect Donald Trump failed in the U.S. House of Representatives on Thursday, leaving Congress with no clear plan to avert a fast-approaching government shutdown that could disrupt Christmas travel.

By a vote of 174-235, the House rejected the spending package, which was hastily assembled by Republican leaders after Trump and billionaire Elon Musk scuttled a prior bipartisan deal. Despite Trump's support, 38 Republicans voted against the package along with all but three Democrats.

Government funding is due to expire at midnight on Friday. If lawmakers fail to extend that deadline, the U.S. government will begin a partial shutdown that would interrupt funding for everything from border enforcement to national parks and cut off paychecks for more than 2 million federal workers. The U.S. Transportation Security Administration warned that travelers during the busy holiday season could face long lines at airports.
