Donald Trump is catching flak for wearing a blue suit to Pope Francis’ funeral, and social media users aren’t holding back their opinions. The president and first lady Melania Trump attended the religious leader’s funeral Saturday. After photos and footage from the ceremony hit the internet, the Republican faced criticism online for his attire.

The first practicing Catholic first lady since Jackie Kennedy, known to express her mood through fashion statements, wore a black lace veil.

Vatican protocol demands that those attending the papal funeral wear a black suit and a black tie. Trump was seen at the event wearing a blue suit and a blue tie. Biden, Zelenskyy also made protocol missteps.
