Former Obama White House chief photographer Pete Souza shaded President Donald Trump ― as he so often did during Trump’s first term ― with a pictorial blast from former President Barack Obama’s past appearance at the United Nations.

After Trump was forced to walk on Tuesday when an escalator at the U.N. stopped with him and first lady Melania Trump on it, Souza posted on Instagram a 2015 image of Obama on what appeared to be the same set of escalators.

Souza paired the snap with an excerpt from Obama’s 2015 U.N. address hailing the “system of international rules and norms,” which Trump, with his rhetoric and policies, is now risking tearing down, a decade ago:

“It is this international order that has underwritten unparalleled advances in human liberty and prosperity. It is this collective endeavor that’s brought about diplomatic cooperation between the world’s major powers, and buttressed a global economy that has lifted more than a billion people from poverty. It is these international principles that helped constrain bigger countries from imposing our will on smaller ones, and advanced the emergence of democracy and development and individual liberty on every continent.”
