U.S. Sen. Marco Rubio hopes Republican gains in midterm elections will breathe new life into efforts to impose sanctions on Venezuelan officials who commit human rights abuses.

The Florida Republican is a sponsor of legislation targeting Venezuela’s socialist government that has been stalled since clearing the Senate Foreign Relations Committee in May with bipartisan support. Similar legislation, which instructs the Obama administration to freeze the U.S. assets of known abusers and commit more American funding to pro-democracy groups in the South American country, has already passed the U.S. House of Representatives.
