On the morning after Christmas, first daughter Ivanka Trump tweeted photos of her husband, Jared Kushner, and son on a boat with the caption, “this fish is a trophy!” But many Twitter users were more interested in something in the background—a Confederate flag.

The controversial symbol of the Confederacy can be seen on a boat in the distance behind Kushner’s left shoulder, displayed alongside the American flag. Twitter users quickly attacked the first daughter, since President Donald Trump, her father, has a history of defending Confederate statues.

“Couldn't find four photos without one? Or is this a dogwhistle?” tweetedWalter Shaub, who was director of the Office of Government Ethics under former President Barack Obama.

The president refused to speak out strongly against white supremacist groups after an August rally in Charlottesville, Virginia, in which a man allied with a far-right group ran over and killed a counterprotester and injured others.

“I think there is blame on both sides,” the president said after the incident. “You had a group on one side that was bad. You had a group on the other side that was also very violent. Nobody wants to say that. I’ll say it right now.”

Later in August, the president said that efforts nationwide to remove Confederate flags and monuments were attempts “to take away our culture” and “take away our history.”

Ivanka Trump came down harder on the Charlottesville violence, tweeting, “There should be no place in society for racism, white supremacy and neo-nazis.”

Some social media users took jabs at Kushner, who is serving as a senior White House adviser under a temporary security clearance because he hasn’t passed a comprehensive background investigation. “Does that fish have a security clearance too,” one Twitter user asked.

Another Twitter user said Kushner is spending time with his family “while he can,” alluding to a probe into possible collusion between the Trump campaign and Russians in the presidential election. Kushner was reportedly involved in a heavily scrutinized meeting at Trump Tower with a Russian lawyer who promised dirt on Hillary Clinton, fueling speculation that he could be implicated.

But some came to the first daughter’s defense. “Do you hold yourself accountable for the actions of the person driving next to you? If not, you’re a hypocrite,” another Twitter user said.

The first daughter also posted the photo, taken at an unknown location, on her Instagram.
