i'm jake tapper. we begin with the politics lead. president trump today is once again claiming he will pursue expanding, quote, meaningful and intelligent back ground checks for gun sales as he has before in the past in the immediate aftermath of mass shootings in the u.s. such as after the massacre in parkland, florida, last year for example. president trump on his way to vacation at his golf club in new jersey said he is talking to congressional leaders including mitch mcconnell who the president claims is, quote, totally on board with this plan. though mcconnell's spokesperson almost immediately disputed that telling cnn mcconnell did not endorse anything in his conversation with president trump. the president has of course promised action on expanding background checks before. he has never followed through. and we should note earlier this year even threatened the president, threatened to veto two bills passed by the democratic-led house to strengthen background checks. pamela brown has more on the president repeating the congress to the american people, the one he's broken many times before.
