Social media cringed at President Donald Trump barging ahead of King Charles in a receiving line with his top administration officials.The 77-year-old king shook hands with Vice President JD Vance, Secretary of State Marco Rubio and other top cabinet officials before begging off halfway through the receiving line, and the 79-year-old president sauntered past and picked up shaking hands where Charles had left off.Charles then offered his hand again but withdrew it after Trump continued shaking hands with his officials as the king stood by awkwardly, and the president's critics cited the encounter as an example of his lack of manners."Classless Trump," huffed Bluesky user Jers_Gal. "Walking in front of the King, not allowing him room to shake hands with the crowd. Charles tried to extend his hand a few times and Trump just kept walking in front of him. The no class, bumbling idiot is a major embarrassment to our country!""Who is it that didn't shake hands with the King?" wondered X user Julia Mac. "Trump stepped over in front of Charles and continued to shake hands, King Charles pushed aside.""Trump has no idea how to treat his guests - he rushed ahead when King Charles was supposed to be inspecting the troops, leaving Charles behind," lamented X user Jay. "He also went in front to shake hands with a line of people - ignoring Charles and his outstretched hand. Very rude." - YouTube www.youtube.com
