The claim by a popular 13-year-old conservative commentator that President Barack Obama blocked him on Twitter appears to be false.

Pearson is a YouTube sensation whose provocative videos critical of Obama reach millions of people. He is also the national chairman of Teens for Ted, a group backing Sen. Ted Cruz (R-Texas) for president.

On Wednesday, Pearson turned to Twitter to allege that he had been blocked by the @POTUS account. That claim, however, was almost immediately refuted by a White House spokesman. Pearson called the spokesman’s denial “outrageous” and responded by uploading a video blasting the president for allegedly lying about the incident.
