Earlier Monday, President Donald Trump tweeted that he had told Murphy to move ahead with plans for a transition, though he reiterated that he believed he would prevail in his legal challenges to the results of the election in several key states.

In a letter to Biden notifying him that the GSA would make federal resources available to him in the event he was certified as the winner of the presidential election, Murphy said she had never been told by the White House to delay the transition.

She added: "I did, however, receive threats online, by phone, and by mail directed at my safety, my family, my staff, and even my pets in an effort to coerce me into making this determination prematurely."

On Sunday, CNN's Jake Tapper told viewers that Murphy would be responsible for the deaths of Americans if she did not begin the transition process, ostensibly because Biden's team would not have information necessary to distribute vaccines provided by Trump's Operation Warp Speed.

"Her actions could very well hamper the Biden team's ability to deal with the pandemic when they take over. It is a matter of life and death," Tapper said, warning that her "legacy will be written in stone."
