Billionaire investor Carl Icahn was on hand Tuesday night for Donald Trump's massive New York GOP primary win.

Trump was projected by NBC to notch a "significant" victory in his home state — where he has conducted much of his real estate business. During his victory speech, the Republican front-runner celebrated the other business leaders in his crowd of supporters, including Icahn.

When asked about the relationship between the two titans of business, Trump said "we just like each other." And for his part, Icahn declared that "Trump is the only candidate who can stop the terrible gridlock in Washington and make Congress work again."

In September, Icahn said that electing Trump should be a "no-brainer" for American voters, especially given his focus on the middle class.

Trump has suggested Icahn would make a good Treasury secretary in his cabinet, but the Icahn Enterprises chairman has repeatedly declined the implied offer.
