By Patricia ZengerleWASHINGTON, Aug 4 (Reuters) - A group of Republican and Democratic U.S. senators on Tuesday called for elections in Venezuela, seven months after ‌President Donald Trump's administration removed then-President Nicolas Maduro and installed his vice ‌president as acting president. Shaheen, the committee's top Democrat, said authorities in Caracas must release all political prisoners and allow all political actors, including Machado, to safely return and participate in political activity. Nobel Peace Prize winner Machado left Venezuela late ​last year to receive her Nobel ​after living mostly in hiding since a contested 2024 presidential election. Trump has denied media reports that his administration told Machado not ​to return. Machado has repeatedly ‌been publicly sidelined by Washington since Maduro's removal, with U.S. officials saying ​she does not have enough support to lead the country.
