From Washington Examiner :
“It must be noted that your ascertainment that Joe Biden and Kamala Harris are the ‘apparent successful candidates’ will not impact President Trump’s ability to pursue any valid legal claims or his efforts to contest the results of the presidential election,” the officials say in an open letter  to Trump.
But the letter also says, “Although counting is still ongoing in some states, the math makes apparent what will soon become official: Joe Biden and Kamala Harris have clearly prevailed. Nor has any evidence been presented in any forum that raises any realistic possibility of changing that result.”
