An excerpt from another article from the same page:
[F]ormer President Donald Trump has more than his share of outspoken critics within Christianity, from the Rev. Raphael Warnock (a Democratic U.S. senator via Georgia) to devout Catholics like President Joe Biden and former House Speaker Nancy Pelosi (D-California). His Democratic opponent in the 2024 presidential race, Vice President Kamala Harris, is a Baptist with a fondness for Hinduism (her mother was from India).
WSJ speculates the impetus of the sell off is due to the potential of Trump cashing in his 2billion worth of shares after the expiration of a lock-up agreement. So, I'm not so sure if that would exactly qualify as a "failed business venture."
