At Pope Francis' funeral, US President Trump faced a stark contrast in reception compared to Ukrainian President Zelensky.

Sleepy, who? Donald Trump became the subject of an online debate as his critics accused him of falling asleep at Pope Francis' funeral. A photo of the president at the former head of the Catholic Church's burial service caused controversy online after Trump had his head down and eyes closed — causing it to look like he had dozed off.

Trump is joining world leaders in Rome for the funeral of the Pope Francis, which as a major set piece of international relations will include informal talks regarding the war in Ukraine, although Russian President Vladimir Putin is not attending.
