The clash in style between Donald Trump and Pope Francis and their positions on migration, the environment and poverty will come into sharper focus with the president in Rome for Francis’ funeral.

Pope Francis's funeral drew global leaders, but Donald Trump's attendance sparked controversy. He deviated from the dress code with a navy suit and was seen using his phone and possibly sleeping during the service.

President Donald Trump was criticized for wearing a blue suit and tie to Pope Francis’ funeral on April 26. However, a Vatican source tells PEOPLE that he did not break protocol.
