But people pointed out that the date listed on the photo was incorrect.
The inauguration occurred on Friday, Jan. 20. The photo listed Saturday, Jan. 21, as the date on the photo.
The Women's March, which drew at least 1 million anti-Trump protesters around the world, took place on Saturday.

On Friday, critics posted side-by-side photos that appeared to show a significantly smaller amount of people at Trump's inauguration in comparison to former President Barack Obama's 2009 inauguration.
In 2009, an estimated 1.8 million people attended Obama's first inauguration. That record number of people beat the previous record, which had been set by former President Lyndon Johnson's 1965 inauguration, which had an estimated 1.2 million attendees.
"This was the largest audience to ever witness an inauguration, period," White House press secretary Sean Spicer said of the crowd at Trump's inauguration during a news conference on Saturday.
Official estimates have not been released with numbers of attendees at Friday's festivities.
