House Oversight Committee Chairman James Comer (R-KY) said Sunday that he is interested to know if special counsel Robert Hur conducted any interviews with President Joe Biden’s brother and son, especially since the House has been conducting its own investigation into the Biden family’s foreign business dealings.

Comer’s statement comes after Hur released a report last week regarding the president’s handling of classified documents, with the report questioning Biden’s mental competency. The Kentucky lawmaker explained he was not surprised the report suggested Biden was not mentally well. He added that he wanted to know if any of the classified documents related to Ukraine or China, two countries in which the Biden family has been accused of being financially involved.
