Washington (CNN) A day after telecom giant T-Mobile announced a $26 billion merger with rival Sprint, nine of T-Mobile's top executives — including its CEO, John Legere -- checked into President Donald Trump's Washington hotel, according to internal VIP arrivals lists obtained by The Washington Post.

The merger between the third and fourth largest wireless service providers in the nation was announced in April and the deal needed approval from the Trump administration.

The nine executives were scheduled to stay between one and three days, and have returned to the hotel repeatedly since then, The Post reported on Wednesday, citing eyewitnesses and hotel documents.

Their visits highlight how countries, interest groups and companies impacted by the Trump administration's choices have patronized the President's private business, the newspaper noted.
