Elsewhere, Republicans have sounded cautious notes about the Biden allegations. Sen. Lindsey Graham (R-S.C.), the ranking member of the Senate Judiciary Committee, acknowledged on Wednsday that Gal Luft’s indictment could undermine portions of the House GOP case against the Bidens. “If his activities as an unregistered foreign agent go to his credibility, if they are accurate, yeah,” Graham told HuffPost. Sen. Mitt Romney (R-Utah), meanwhile, said hasn’t seen any evidence yet of a link between Hunter Biden’s “unsavory” business dealings and Joe Biden, which some House Republicans have alleged.
