Congressional Republicans have issued legal summons to several members of the Biden family in an escalation of their impeachment inquiry into the president.
The House Oversight Committee subpoenaed Mr Biden’s son Hunter, his brother James, and Biden family associate Rob Walker.
It is also requesting transcribed interviews with five others.
The White House accused Republicans of “abusing their power to conduct a smear campaign”.
House Republicans opened their impeachment inquiry in September, saying they had uncovered evidence of President Biden’s knowledge of and role in his family members’ domestic and foreign business dealings.
But at the Oversight Committee’s first hearing that month, witnesses and even Republicans on the panel said more evidence was needed to determine if the president had committed any impeachable offenses.
