FedEx executives have been meeting with President Donald Trump about playing a part in the White House's push for public-private partnerships to help fund $1 trillion in spending to overhaul the nation's infrastructure systems, including airports, a source told CNBC's Jim Cramer.

"The president has met and is meeting with the people who run FedEx," Cramer said on "Squawk on the Street" on Monday, citing a source. "I think you're going to hear, and this is my reporting, that FedEx is going to be involved."

"That's a very good reason to own FedEx beyond the numbers," Cramer argued, saying FedEx reports earnings later this month. "I think it will be a good quarter."

Last week, President Trump urged Congress to privatize the U.S. air traffic control system, saying it would make U.S. airports more efficient.

FedEx told CNBC in a statement:

"We are pleased that the proposed budget lays solid groundwork for infrastructure modernization and an independent, non-governmental air traffic control system that will allow more flights to operate safely in congested air space and at crowded U.S. airports. While FedEx strongly supports the need for funding an updated and improved system, it is also essential that the cost accounting going forward reflect airline usage, which is a key indicator for system maintenance and growth."

The White House was not immediately available to respond to CNBC's request for comment on Cramer's reporting.
