But Twitter users went wild over another, much less serious issue: Canadian Prime Minister Justin Trudeau's eyebrows.
A video posted of Trudeau delivering a press conference appeared to show Trudeau's left eyebrow "falling off" his face.
"Trudeau eyebrows" started trending on Google, and Twitter users began rapidly speculating that Trudeau wears fake eyebrows glued to his face. Many had a little fun at his expense:
Someone even created a parody account for Trudeau's eyebrows:
But it doesn't seem like Trudeau has fake eyebrows after all. Several people pointed out that his brows are naturally thicker and darker on the bottom and get thinner and lighter toward the top.
That combined with harsh, unflattering studio lights created the optical illusion of an eyebrow "falling off" his face.
