House Oversight Committee Chairman James Comer said over the weekend that the GOP-led impeachment inquiry into President Joe Biden is likely to lead to “multiple” criminal referrals, though it’s unclear whether his Justice Department will act on them.

The Kentucky Republican made the announcement during a Fox News interview while revealing plans to hold a public hearing this week though first son Hunter Biden has declined to take part after providing private testimony. Earlier, Biden’s attorney said his client would participate in a public hearing.

“If he does not show up, then it’s not going to end well for the Bidens, because we have three witnesses that … have already testified under oath to significantly different stories as to what exactly the Biden influence peddling schemes were,” he told “Sunday Morning Futures” anchor Maria Bartiromo.

“This is very serious because we’re at the point now of criminal referrals,” Comer added.
