Joe Biden hasn’t chosen a vice presidential nominee yet, but the preemptive attacks are already underway online and among conservative commentators.
One of their targets is Susan Rice, a former senior official in President Barack Obama’s administration.
Aides and allies of President Donald Trump have focused on two episodes in particular: Rice’s involvement in the administration’s response to the 2012 killing of four Americans in Benghazi, Libya, and her role in "unmasking" of Trump’s incoming national security adviser, Michael Flynn, from intelligence reports. During the former, she was serving as ambassador to the United Nations; during the latter, she was national security adviser.
One of the most direct attacks came from Fox News host Tucker Carlson, who called her "a threat."
