It’s still unclear whether the smoke around Hunter Biden’s foreign financial connections actually indicates a fire. That’s what federal investigators are (and should be) exploring. But here’s what’s already clear about the investigation into President Joe Biden’s son: The president hasn’t responded by firing people, publicly lashing out at investigators or otherwise obstructing justice. Instead, he has responsibly stayed out of it. What a refreshing change from his predecessor’s campaign of obstruction and vengeance in response to legitimate questions about his own foreign entanglements.
