Sen. Patrick Leahy (D-VT), the president pro tempore of the Senate, was released from a local hospital late Tuesday after being taken there “out of an abundance of caution” when he felt unwell earlier, a spokesperson said. Leahy, who is due to preside over Trump’s impeachment trial in the Senate, was said to be resting at home after undergoing testing at the hospital. A spokesperson confirmed that Leahy underwent a “thorough examination” but gave no further details. Leahy, 80, was present earlier Tuesday as senators were being sworn in as members of the jury for the impeachment trial. After he began to feel unwell in his office, he was examined by the Capitol attending physician before being taken to a hospital for observation. Leahy, 80, is third in line in the order of presidential succession.
