Washington - Former US vice president Joe Biden dropped teasing hints Tuesday that he could soon announce a 2020 White House campaign, telling an enthusiastic crowd that he may need their energy "in a few weeks."
The Democratic elder statesman has been mulling a challenge against President Donald Trump for months.
While he tops nearly all early polls for the Democratic nominations race, strategists and election observers have stressed he is under pressure to enter the crowded field soon, or bow out.
Much about Biden's address to the International Association of Fire Fighters in Washington suggested he is in: attendees waving printed "Run Joe Run" placards; recollections from his blue-collar roots; criticism of the current president without naming him; and soaring oratory about America's leadership role in the world.
"I appreciate the energy you showed when I got up here," the 76-year-old told the fire fighters after several chanted "Run Joe run!"
