Biden's Education Secretary responds to student-loan borrowers with private debt who don't qualify for federal relief: 'We can control our loans. We can't control other loans'

• Education Sec. Miguel Cardona pushed back on opponents who say Biden's debt relief is unfair to those with private loans.
• He said the department "can't control other loans," responding to those with private debt.
• The Supreme Court heard oral arguments to the federal relief plan on Tuesday.

President Joe Biden's federal student-loan forgiveness is being hotly debated — but those holding private debt are largely left out of the conversation.
