Vice President JD Vance has emerged as President Donald Trump’s lead attack dog on the government shutdown as some Democrats lambaste what they see as a lack of White House leadership. As she looked on with a near-constant smile, Vance went after congressional Democrats with a confident and sometimes-charming demeanor. “And it’s craziness.”Vance kept up the anti-Schumer messaging later in the day before a packed room of journalists at the White House. One former aide to House Republican aides gave Vance high marks for his performance so far as Trump’s lead shutdown voice. They have painted Vance and Trump as purposely refusing to extend health care subsidies on which many Americans depend.
