Pete Souza, the former White House photographer for President Barack Obama, continued his crusade of needling President Donald Trump at every turn Thursday.

Souza shared a photo of Obama and his then-chief of staff Bill Daley under a portrait of President Ronald Reagan with the caption “being respectful.” He posted the photo on the same day former Republican vice presidential nominee Sarah Palin and musicians Ted Nugent and Kid Rock posted a photo mocking Hillary Clinton’s White House portrait.

Souza has made his Instagram account a subtle clap-back machine, posting photos as sly response to Trump, including posting photos of Obama speaking with refugees and a photo of former Supreme Court nominee Merrick Garland.
