"I just think they need to do things quickly. If it's hearing a case, do it quickly. If it's an appeal, do it quickly," Trump's remaining Republican opponent told Scripps News in an exclusive interview. 

The comments come as Haley campaigned in Virginia ahead of the March 5 Super Tuesday primaries there and in 15 other states and territories. It is also one day after the Supreme Court further delayed one of the cases against Trump by agreeing to hear arguments on whether or not he should be immune from criminal prosecution for actions taken while president. 

In a wide-ranging interview, Haley discussed other key campaign issues including immigration and the border, whether Trump and President Joe Biden are too old and the future of the Republican party. 

"We have to look at the fact, the Republican Party used to be the party of fiscal discipline. We used to be the party of smaller government. The problem is under Donald Trump, he changed all that he put us $8 trillion in debt in just four years, more than any other president," she said.

"Look at what happened to national security. It used to be peace through strength. Now we see that under Donald Trump he's making it more isolationist. He's siding with Putin over our allies that stood with us at 9/11," the former governor of South Carolina added.
