Check out this video we got of the former President all tux’d up for a reception that went down Saturday night at Trump’s fortress of solitude, Mar-a-Lago, where the former chief himself got on the mic at one point to say a few words for the happy couple, John and Megan Arrigo … but this speech would have nothing to do with the couple… it’s all about him.

Before everyone knew it, he was launching into politics … singing the same ol’ song about false claims the election was rigged.

Watch for yourself — DT rails on the Biden administration over what he considers shortcomings in the early months of his presidency, including foreign policy/deals with China and Iran … plus, Trump goes in on the border situation which is now drawing national attention.
