The conversations among the president and senior aides stem in part from their disappointment that Wray in particular but Barr as well have not done what Trump had hoped — indicate that Democratic presidential candidate Joe Biden, his son Hunter Biden or other Biden associates are under investigation, these people say. Like others, they spoke on the condition of anonymity to disclose internal discussions.

In the campaign’s closing weeks, the president has intensified public calls for jailing his challenger, much as he did for Hillary Clinton, his opponent in 2016. Trump has called Biden a “criminal” without articulating what laws he believes the former vice president has broken.

People familiar with the discussions say Trump wants official action similar to the announcement made 11 days before the last presidential election by then-FBI Director James B. Comey, who informed Congress he had reopened an investigation into Clinton’s use of a private email server while she was secretary of state after potential new evidence had been discovered.
