That's a John Bolton tweet quoted in the piece. Full context:

> On March 14, 2020, John Bolton described the changes made to the team as streamlining. He tweeted: “Claims that streamlining NSC structures impaired our nation's bio defense are false. Global health remained a top NSC priority, and its expert team was critical to effectively handling the 2018-19 Africa Ebola crisis. The angry Left just can't stop attacking, even in a crisis.”
