President Trump awarded four tech leaders the National Medal of Science on Thursday. Elon Musk, Jensen Huang, Sergey Brin, and AMD’s Lisa Su received the honor at the Golden Age of American Innovation Summit. Michael Dell and Microsoft’s Satya Nadella were given the National Medal of Technology and Innovation.

According to The New Republic, these awardees have donated nearly six billion dollars to efforts tied to Trump and his administration. Alphabet and Microsoft contributed to his inauguration fund and a White House ballroom project. AMD backed a pro-Trump Super PAC. Michael and Susan Dell pledged six point two five billion dollars toward Trump Accounts, a children’s savings program.

Trump said the honorees helped “pioneer an incredible future for America.”

Notably, Nadella received his medal just after Microsoft was suspended indefinitely from the H-1B visa program.
