At Pope Francis's funeral, more than 170 national leaders from around the world attended. However, U.S. President Trump's behavior drew quite a bit of criticism, including being spotted chewing gum and looking at his phone during the ceremony.
When paying final respects to the Pope, everyone, like French President Macron and his wife, stood about a meter from the carpet in front of the coffin. However, Trump and First Lady Melania were at zero distance, with Trump even standing directly on the carpet.
Additionally, during the ceremony, Trump sat in the front row, very conspicuously. He brazenly took out chewing gum and chewed it, and not long after, he was also spotted sneaking a look at his phone, although he tried to cover it with his hand, it was still quite obvious.
On that day, all heads of state representatives wore black clothing, except for Trump who wore a blue suit. These various inappropriate behaviors sparked controversy and were heavily criticized as improper and disrespectful.
