WASHINGTON – Looking to undermine Democratic rival Joe Biden, President Donald Trump’s campaign is pushing a familiar line of attack: unverified allegations about Biden's son and his foreign business ties.

But reporting in the New York Post, and the emergence of a man who says he worked with Hunter Biden, have raised more questions than answers, including about the authenticity of emails at the center of the story.

The renewed allegations trace back to Trump lawyer Rudy Giuliani, who has repeatedly pushed unfounded claims about the Bidens. Even if the emails in the Post are legitimate, they do not validate claims that Biden’s actions were influenced by his son’s business dealings.

A look at developments:

HOW DID BIDEN’S SON BECOME A CAMPAIGN ISSUE?

Hunter Biden joined the board of the Ukrainian gas company Burisma in 2014, around the time his father, then vice president, was helping conduct the Obama administration’s foreign policy with Ukraine.

Senate Republicans said in a recent report that the appointment may have posed a conflict of interest, but they did not present evidence that the hiring influenced U.S. policies.

Trump and his supporters, meanwhile, have advanced a widely discredited theory that Biden pushed for the firing of Ukraine’s top prosecutor to protect his son and Burisma from investigation. Biden did indeed press for the prosecutor’s firing, but that’s because he was reflecting the official position of not only the Obama administration but many Western countries and because the prosecutor was perceived as soft on corruption.
