President Joe Biden's student loan forgiveness plan could cost as much as $24 billion a year, White House press secretary Karin Jean-Pierre told CNN Thursday evening.

Pressed by Lemon on whether the White House would release a detailed cost estimate, Jean-Pierre said they would share more details after seeing how many Americans take advantage of the plan.

The White House struggled for a second day to answer questions about Biden's plan, claiming at the same time that the president had waited to be

fiscally balanced" before unveiling the plan and had no way of knowing how much the plan would cost.

In a news briefing early Thursday, Jean-Pierre insisted that the plan to cancel tens of thousands of dollars in federal student loan

debt for millions of Americans "will pay in full for what this president has done with the economy."
