"Trump dumps Director of National Intelligence, Admiral McGuire, because his staff briefed the House Intelligence Committee, as directed by law, to report Russian interference in the 2020 election."
Hillary is not running for office and therefore does not have an incentive to pay for another dossier full of Russian disinformation. No one in the obama administration briefed the intelligence Committee about Hillary, the DNC and her work with Russia to undermine the 2016 election. Instead, they helped spread the Russian disinformation.
Had President Trump told Admiral McGuire not to brief Congress, Admiral McGuire is required not to do so. Nor is there any 2020 Russian interference to report. Again, Hillary is not running for office in 2020.
