White House staffers have been working tirelessly this week to ensure President Trump’s ability to live-tweet during James Comey’s Senate testimony tomorrow is unimpaired.Explaining his absence from Monday’s press briefing, Sean Spicer said, “Monday’s brainstorming session produced a solution which enables the President to stay hydrated while tweeting, and I think Mike’s prototype does just that. Today’s press briefing will be canceled as Sarah and I build the production version for tomorrow’s hearing.”
