President Joe Biden took a swipe at former President Donald Trump during a press conference on Thursday after Trump needled Biden over his prisoner swap deal with Russian President Vladimir Putin. “President Trump has said repeatedly that he could’ve gotten the hostages out without giving anything in exchange. What do you say to that,” a reporter asked Biden on his way out of the press conference. Grinning ear-to-ear, Biden responded, “Why didn’t he do it when he was president,” and then he walked off the stage with his thumb up. “So when are they going to release the details of the prisoner swap with Russia,” Trump wrote in his Truth Social post. “Just curious because we never make good deals, at anything, but especially hostage swaps,” he added. Many of the details of the deal are unknown currently, aside from there being 26 people and seven countries involved. The prisoners swapped included Russian hitman Vadim Krasikov, who shot a Georgian national in broad daylight in central Berlin. Sen. J.D. Vance (R-OH) told CNN that the deal was initiated because “bad guys all over the world recognized that Donald Trump’s about to be back in office, so they are cleaning house.”
