Amy Coney Barrett joins liberal Supreme Court justices in scrutinizing a student-loan company's involvement in one of the lawsuits blocking Biden's debt relief

• Amy Coney Barrett questioned whether a group of GOP-led states have standing to block Biden's student-debt relief.
• The court's three liberal justices also focused on standing during Tuesday's oral arguments. 
• The states said the relief would harm Missouri-based student-loan company, MOHELA.

Justice Amy Coney Barrett, a conservative, questioned whether a group of Republican-led states can legally challenge President Joe Biden's student-loan forgiveness, similar to points raised by the Supreme Court's three liberals on Tuesday.
