Republican Rep. Devin Nunes, the ranking member of the committee, falsely alleged in his opening statement that former vice president Joe Biden boasted of pressuring Ukraine to fire a prosecutor, Viktor Shokin, "Who happened to be investigating Biden's own son."
There is no evidence Biden's son, Hunter Biden, was ever under investigation.
As we explained in this detailed fact check, the investigation was into the business dealings of Mykola Zlochevsky, who owned a natural gas company, Burisma Holdings, for which Hunter Biden had sat on the board of directors.
And it's unclear even if the investigation into Zlochevsky was active at the time Biden applied his pressure on the Ukrainians. Former deputy prosecutor Vitaliy Kasko, who had resigned alleging corruption in the prosecutor's office, told Bloomberg News this year that the investigation had been allowed to become dormant.
