Special counsel David Weiss is planning to feature highly personal testimony about Hunter Biden‘s drug addiction during his trial on felony gun charges, seeking the testimony of three past romantic partners — including the first son’s ex-wife.

The expected prosecution witnesses in Biden’s trial include his ex-wife, Kathleen Buhle; Lunden Roberts, an Arkansas woman with whom he had a daughter; and Beau Biden’s widow, Hallie Biden, whom he also dated.
