When he's having working lunches or dinners at the White House, President Donald Trump often wields salt and pepper shakers almost twice the size of everyone else's.

This could be another one of his power moves, alongside his fierce handshakes and bulky suits.

Photos show Presidents Bill Clinton, George W. Bush, and Barack Obama using the same size shakers as their White House guests, while Trump's usually tower over others.

President Donald Trump displays his power with firm handshakes, a second scoop of ice cream, and towering salt and pepper shakers.

Mark Knoller, CBS News' White House correspondent, pointed out how much bigger Trump's shakers were in a tweet on Thursday.

Insider combed the photo archives and found that Trump more often than not gets much larger salt and pepper shakers than other foreign leaders or American politicians when dining at the White House. And we couldn't find instances of Trump's most recent predecessors using larger shakers than those of their guests.

The large shakers might just be because he enjoys salty foods like KFC chicken, Big Macs, and bacon and eggs. But it could also be another power move, alongside his fierce handshakes and bulky suits.

These photos show how much bigger Trump's White House salt and pepper shakers usually are than everyone else's, and how they compare to those of Presidents Bill Clinton, George W. Bush, and Barack Obama.
