Amid growing concerns over US President Donald Trump's health, his deputy, JD Vance, believes he is ready to take charge as America's commander-in-chief in case of any "terrible tragedy." The Vice President, however, reassured that Trump is in "good shape" to complete his four-year term in the White House. In an interview with USA Today, Vance recalled setting foot in the Oval Office for the first time in January and being "overwhelmed" by its "grandeur" and "incredible history." Addressing concerns about the 79-year-old Trump's health, Vance said, "The president is in incredibly good health...He's got incredible energy." Vance's remarks came amid growing concerns about Trump's health after a large bruise was seen on the president's hand during his meeting with South Korean President Lee Jae Myung.
