President Biden appears to have erased Dr. Seuss from "Read Across America Day", the annual celebration of reading in honor of the legendary children's author, whose birthday falls on March 2.

While Biden followed presidential tradition in proclaiming Tuesday "Read Across America Day," he bucked his predecessors by leaving out any mention of Dr. Seuss from the proclamation.

The White House didn't immediately return a request for comment on why Dr. Seuss was left out of the proclamation, but the snub comes as progressives have sought to cancel the beloved children's author. 

One of Virginia's biggest school districts, Loudoun County Public Schools, reportedly nixed Dr. Seuss from the school's "Read Across America Day" celebration, citing alleged racial "undertones" in his children's books.

Former President Barack Obama and former President Donald Trump both highlighted Dr. Seuss' contributions in their annual proclamations, a Fox News review of White House archives found.

"The works of Theodor Seuss Geisel, better known to us as Dr. Seuss, have sparked a love for reading in generations of students.," Obama said in his 2015 proclamation. "His whimsical wordplay and curious characters inspire children to dream big and remind readers of all ages that 'a person's a person no matter how small." 

Obama's 2016 proclamation described Seuss as "one of America's revered wordsmiths" who "used his incredible talent to instill in his most impressionable readers universal values we all hold dear."

Trump, in his 2018 proclamation, urged Americans to "always remember the still-vibrant words of Dr. Seuss: 'You have brains in your head. You have feet in your shoes. You can steer yourself any direction you choose.'" 

Then-first lady Melania Trump celebrated Read Across America Day in 2017 by reading Dr. Seuss books to hospitalized children.

"Dr. Seuss has brought so much joy, laughter and enchantment into children’s lives all around the globe for generations," Melania said at the time.

"Through his captivating rhymes, Dr. Seuss has delighted and inspired children while teaching them to read, to dream, and to care."
