Joy Reid leads this episode of The ReidOut with Donald Trump bragging again about acing a dementia test, meanwhile claiming that presidents should have full immunity for any crimes they might want to commit. Former U.S. Attorney General Eric Holder joins Joy on that, and on a big victory in Louisiana where a new legislative map, with two majority-Black districts, is advancing in the state legislature. Next, with a border deal on the table, which Senate Republicans say is a great deal, Trump's MAGA caucus in the House is saying no, because they want to continue to stoke fear ahead of the fall election. All this and more in this edition of The ReidOut on MSNBC.
