And it kicked into overdrive last week when Trump seized upon revelations that Biden was informed of the investigation of ties between Russia and Michael Flynn, a senior Trump official, as evidence of a plot to undermine a presidency before it began.
And it was Trump’s push for Ukraine to find politically damaging dirt on the Bidens that led to the president’s impeachment.
Trump’s Senate allies will hold hearings into the younger Biden’s work overseas to portray the former vice president as a longtime Washington insider whose family benefited from his stature.
“From his involvement in the unmasking of General Flynn to his son Hunter Biden repeatedly landing lucrative foreign business deals while his father was vice president, Joe Biden embodies the D.C. swamp,” said Trump campaign spokeswoman Sarah Matthews.
Biden allies display something approaching amusement as they tick through the attacks Trump has leveled against the former vice president, including calling him “Sleepy Joe.”
