evidence: From 2013 through 2018 Hunter Biden and his company brought in about $11 million via his roles as an attorney and a board member with a Ukrainian firm accused of bribery and his work with a Chinese businessman now accused of fraud, according to an NBC News analysis of a copy of Biden’s hard drive and iCloud account and documents released by Republicans on two Senate committees. [...] "No government ethics rules apply to him," said Walter Shaub, a former director of the U.S. Office of Government Ethics who is now an ethics expert with the Project on Government Oversight. Shaub added, however, that "it’s imperative that no one at DOJ and no one at the White House interfere with the criminal investigation in Delaware." Shaub had previously raised questions about Hunter Biden’s new line of work, selling his own paintings, which created the potential to purchase a painting to buy perceived influence, and also because the White House became involved in the transactions, arranging that none of the buyers’ names be known to Biden, the White House or the public. [...] NBC News obtained a copy of Biden’s laptop hard drive from a representative of Rudy Giuliani and examined Biden’s business dealings from 2013 to 2018 based on the information available on the hard drive and the scope of the documents released by the Senate.
