The rumors of an American flag ban at the Democratic National Convention spread quickly online Tuesday after photos of delegates in Philadelphia seemed to show a lack of the Stars and Stripes.

The controversy started one day after the Democrats kicked off the first day of their convention to officially nominate Hillary Clinton.

The lively online discussion even prompted a comment from Eric Trump, son of Republican presidential nominee Donald Trump:

The absence of American Flags at the #DNC further reinforces the "commercial sterilization" message of my speech! 🇺🇸 pic.twitter.com/AAZKpSHgxp — Eric Trump (@EricTrump) July 26, 2016

The rumors seem to have originated with online blogs that pointed to stage shots showing speakers in front of a digital backdrop that didn't include U.S. flags. In fact, the digital screen - much like the one used by the GOP in its Cleveland meeting - did contain images of the American flag that rotated with other solid-colored and patterned backdrops.

Images from the convention show an array of backdrops:

What's banned at DNC 2016?

Flags are not banned from the convention center, either, according to the DNC website's list of security information. There are some items that are prohibited, including: backpacks, large bags, balloons, drones, e-cigarettes, noisemakers, selfie sticks or any kind of weapon.

The list of prohibited items also included placards or signs brought in from outside the convention.
