If any U.S. military forces are currently in Venezuela without Congress having formally voted to declare war or approve their use there, this resolution would require the President to pull them out. It's essentially Congress asserting its constitutional role in deciding when the country goes to war, rather than letting the President keep troops engaged in another country on his own authority alone. This would affect U.S. troops potentially stationed or operating in or around Venezuela, as well as the President's ability to continue any such military action without lawmakers' explicit sign-off.
