WASHINGTON (AP) - Democrats are moving quickly to try to roll back President Donald Trump's declaration of a national emergency to siphon billions of dollars from the military to fund construction of a fence along the U.S.-Mexico border.
  
Tuesday's vote in the Democratic-controlled House comes on legislation to revoke Trump's executive order from earlier this month and would send it to the Republican-held Senate, where it would take only a handful of GOP defections to pass it.
  
Trump is likely to prevail in the end since he could use his first-ever veto to kill the measure if it passes Congress, but the White House is seeking to minimize defections among the president's GOP allies to avoid embarrassment.
