Nov 23 (Reuters) - The United States is in talks with Mexico and other countries to facilitate the return of Venezuelan migrants to their homeland, a senior U.S. official said in a call with reporters on Tuesday. "We're in discussion with Mexico and other countries to see what can be done in that sense," said Blas Nunez-Neto, the acting assistant secretary for U.S. border and immigration policy. Nunez-Neto declined to provide details when asked which other countries were in talks with the United States. A U.S. federal judge invalidated Title 42 last week but then a Republican-led legal challenge was filed seeking to keep it in place. Return flights of Venezuelans from Mexico began last month, Mexican officials told Reuters.
