Trump has told sources that he expects to appoint three more Supreme Court Justices before the end of his first term, Axios reports.

Trump has already nominated conservative judge Neil Gorsuch​, who was confirmed and then sworn into office in April of 2017. Gorsuch replaced ​the late Justice Antonin Scalia. Trump believes that Associate Justice Anthony Kennedy, who​ is 81 years old, will soon be out. Kennedy is rumored to be considering retirement.

"Ok," one source told Trump, "so that's two. Who are the others?"

"Ginsburg," Trump replied. "What does she weigh? 60 pounds?"

"Who's the fourth?" the source asked.

"Sotomayor," Trump said, referring to the relatively recently-appointed Obama justice, whose name is rarely, if ever, mentioned in speculation about the next justice to be replaced. "Her health," Trump explained. "No good. Diabetes."

Associate Justice Ruth Bader Ginsburg is 84 years old, while Associate Justice Sonia Sotomayor is just 63 years old. Sotomayor, who was appointed by President Obama, is the first Latina to serve on the Supreme Court. She was diagnosed with diabetes as a child. 

Ironically, Trump is the oldest person to be elected president in U.S. history. The reality television star is 71 years old.

One source is quoted as saying, "it's all about the numbers for him," which is not surprising because we are talking about a man who constantly brags about numbers, whether it be rating numbers, the size of the crowd at his inauguration or crowds for his rallies in general.
