President Donald Trump could soon find himself with a second Supreme Court vacancy to fill – perhaps in just a few months.

'I would expect a resignation this summer,' Iowa Republican Sen. Chuck Grassley said Tuesday in his home state.

Grassley chairs the Senate Judiciary Committee, which would find itself asked to vet another justice just months after confirming Neil Gorsuch.

The last time two associate justices were confirmed in the same calendar year was 1971, during the Nixon presidency.

Senate Judiciary Committee Republican chairman Charles Grassley said Wednesday in his home state of Iowa that he expects there will be another vacancy in the high court as soon as this summer

President George W. Bush, however, had two confirmation fights just four months apart in 2005 and 2006 – the only two appointments he would make to the high court.

Grassley said Tuesday during a Q&A session in the town of Muscatine that he expects Trump to continue to choose justices from a list of potential nominees he released before the November election.

And that could signal that the Supreme Court spinner will land on someone other than a white male the next time around.

'I don't know about racial and ethnic divisions, but there's some very good females on there that would make good Supreme Court Justices as well,' Grassley said.

It's unclear which justice he expects to step aside. Like all federal judges, Supreme Court justices have lifetime appointments that only they can shorten by voluntary retirement.

Anthony Kennedy, currently the longest-serving Supreme Court jurist, has been rumored to be on his way out since late last year.

Kennedy was conservative president Ronald Reagan's final nominee, but is now seen as a centrist swing-vote on social issues – so much so that replacing him with a right-winger would alter the balance of power for a generation.

Justice Ruth Bader Ginsburg, the court's oldest justice at 83 years of age and one of its most liberal voices, is perennially rumored to be sick – then healthy, then sick again.

'At my age, you have to take it year by year. I know this year I’m okay,' she said in 2016 during an interview with ABC News.

Ginsburg also revealed that even at her advanced age, she can do 20 pushups.

'I do 10, and then I breathe, and then I do 10 more,' she said.

Ginsburg has survived both colon cancer and pancreatic cancer, but has let it be known that she doesn't want a Republican president replacing her, lest the court tilt too far to the right.

Texas Sen. Ted Cruz, another Republican who sits on the Judiciary Committee, said last week that 'I think we're likely to see another vacancy potentially as soon as this summer.'

Whether Trump gets to name another justice this year, next year, or even in 2019 – presuming Republicans maintain their majority in the upper chamber of Congress – Republicans will find a smooth path in front of them.

This year Senate Majority Leader Mitch McConnell successfully changed a Senate rule that had required a 60-vote supermajority to end debate on a Supreme Court nominee. Now that threshold is just 51 votes.
