Aides Struggle To Soothe A President Rattled By Joe Biden
President Donald Trump has publicly expressed confidence that he could easily best Joe Biden in a 2020 battle.
But behind closed doors, Politico reports the president has fixated on Biden, despite reassurances from top aides.
Trump has demanded multiple updates on how Biden is faring in early Democratic primary polls.
That's a sign of how seriously Trump takes the potential candidacy.
Biden has topped several recent battleground state polls.
