If (and it’s a big if) Trump has anything, it’s almost certainly related to the documents he challenged Obama to release, not a divorce filing.
More likely, Trump is trying just to make himself useful by applying his own penchant for attention-whoring to overshadow Allred’s similar, but less-well-honed vanity.
Trump had nothing, it was just an offer to donate 5 million to a charity if Obama gave up all his papers.
Obama has used more than that just to hide his BC. Stupid idiot Trump stunt.
This is one bitter hateful divorcee - no wonder the husband moved on.
