JOHANNES EISELE/AFP via Getty Images Senate Minority Leader Chuck Schumer and Rep. Alexandria Ocasio-Cortez held a joint press conference on Sunday to discuss options for blocking Republicans from filling the Supreme Court vacancy left by the death of Justice Ruth Bader Ginsburg. Ocasio-Cortez, in response to a reporter's question, said Congress should not rule out impeachment of either US Attorney General Bill Barr or President Donald Trump, which would delay any Senate confirmation vote. "It's extraordinarily important that we understand the stakes of this vacancy," Ocasio-Cortez said.
