Two influential Republican U.S. lawmakers have urged President Joe Biden to prevent a French company from working on civil nuclear power projects with Russia's state-owned nuclear company Rosatom, saying doing otherwise would help fund Russian President Vladimir Putin's war in Ukraine. In a letter seen by Reuters, Representative Michael McCaul, chairman of the House of Representatives Foreign Affairs Committee, and Senator Jim Risch, the top Republican on the Senate Foreign Relations Committee, urged Biden to not waive sanctions on Russia, saying it would allow French-owned Electricite de France, or EDF, to engage in nuclear power projects with Rosatom.
