The state of Illinois recently celebrated its very first Obama Day holiday, and as the day wound down, a list of Hollywood notables jumped to Twitter to celebrate the former president’s birthday.

Illinois’ Obama Day holiday is not a full-fledged holiday, of course. When the day was adopted, lawmakers made sure that no state workers would get the day off nor are they paid for the day, for instance. Further, the holiday was scheduled during the summer, and on Barack Obama’s birthday, so schools do not have to recognize it.

In effect, the day is not on the regular holiday list and was implemented more as a political sop than a real celebration. But that did not prevent Hollywood from celebrating the day and conversely lamenting the “reign of error” under President Donald Trump, Deadline Hollywood exclaimed.

Former Vice President Joe Biden, for one, jumped to Twitter to celebrate his former boss’s birthday.

Our lunches together were a highlight of every week at the White House. Last week's trip to @DogTagBakery was no different. Happy birthday to my brother, my friend, @BarackObama. pic.twitter.com/0faYjvnPW6 — Joe Biden (@JoeBiden) August 4, 2018

A long list of Hollywood stars also raced to social media to celebrate the day. Selma director Ava DuVernay tweeted out how thrilled she was to have met Barack Obama:

Thank you, @BarackObama. It is an honor to be in the world at the same time as you. Let alone the same room. #ObamaDay pic.twitter.com/O3IyABxY1B — Ava DuVernay (@ava) August 4, 2018

Singers John Legend, Janelle Monae, and Common also tweeted a note to the former president:
