(Doug Mills | The New York Times) President Joe Biden delivers remarks on the American Rescue Plan in the Rose Garden of the White House in Washington, March 12, 2021, as Vice President Kamala Harris and Senate Majority Leader Chuck Schumer (D-N.Y.) look on. Twenty-one Republican attorneys general pressed the Biden administration on March 16 to clarify a provision in the $1.9 trillion economic aid package that the president signed into law last week, warning that its restrictions on state efforts to cut taxes could be “the greatest attempted invasion of state sovereignty by Congress in the history of our Republic.”
