Sept. 23 (UPI) -- The White House-appointed director of the country's 250th birthday celebration was fired Tuesday after allegedly making unapproved social media posts and financial decisions.

Ariel Abergel, 25, was the executive director of the bipartisan Semiquincentennial Commission to celebrate the anniversary of the signing of the Declaration of Independence next year. Before his appointment by President Donald Trump, he was a producer of Fox & Friends Weekend on Fox News.

Abergel was fired after he "initiated a security breach of a commission social-media account, attempted to procure the resignations of multiple commissioners by misrepresenting himself as acting on behalf of congressional leadership, and engaged in multiple other serious and repeated breaches of authority and trust," a spokesperson for America250 told The Wall Street Journal.

The spokesperson also said Abergel did things that threatened the "Commission's operations and reputation" by defying directives from the executive committee and independently approving programming, finances and communications without permission, The Hill reported.

The commission is made up of 16 unpaid private citizens, eight members of Congress and 12 federal officials who serve as nonvoting ex-officio members supported by the America250 foundation.

Also on the committee are Defense Secretary Pete Hegseth, Attorney General Pam Bondi, Secretary of State Marco Rubio and Sen. Alex Padilla, D-Calif.

Sources familiar with the matter told the Journal that Abergel tried to steer the theme of events toward honoring Trump.

But Abergel told the Journal that the foundation is spreading "malicious lies" to "distract from the truth." He said he was fired for posting on social media to honor slain conservative activist Charlie Kirk.

"America is in mourning. God bless Charlie Kirk," read the post on Instagram under the America250 account, alongside a photo of Kirk. Abergel said he had first asked America250 to make a statement about Kirk before doing it himself.

Abergel told the Journal he was first suspended over the post, then was asked to resign and then was fired.

Though he was fired, a White House official, in a statement, said the administration "is incredibly proud of all of Ari Abergel's work at America250 -- most notably during the Army250 parade, which boldly honored the bravery and strength of our military men and women."
