First lady Melania Trump encouraged the President to start shaking hands with other world leaders during Pope Francis’ funeral Saturday. At one point during the three-hour Catholic mass, attendees were invited to share the “sign of peace” by shaking hands with one another.

The office of President Zelensky shared a picture of Trump and Zelensky engaged in conversation at St. Peter’s Basilica.

The president said he was attending out of respect for Pope Francis but held a brief meeting with Ukrainian President Volodymyr Zelensky.
