House Republicans leading the investigations into President Joe Biden and his son will subpoena Biden’s son, Hunter, House Speaker Kevin McCarthy said Sunday. But when that will happen is still up in the air.

“Hunter Biden will get subpoenaed, but when is the appropriate time? Do you do it because television wants it?” McCarthy said during an interview on Fox News’ “Sunday Morning Futures” with host Maria Bartiromo.

McCarthy launched an impeachment inquiry into President Joe Biden on Tuesday over allegations related to his son’s business dealings that so far have not been backed up by public evidence. But launching the inquiry will allow Congress to find answers to questions Republicans still have about the president’s level of involvement in Hunter Biden’s business affairs, McCarthy said.
