Team owner Bob Kraft is a longtime Trump friend.
Though the committee didn't reveal how much of the funds are left over, the remaining amount will be donated to charity. It also raises a new round of questions about the influence of money in politics, this time for a president who promised to "drain the swamp" of Washington.
President Donald Trump's inaugural committee announced a record-breaking fundraising haul - almost double the record set by then-President Barack Obama in 2009 - for the festivities surrounding his inauguration.
Barack Obama's historic first inauguration collected a net of $53 million in 2009; Obama's team took in $44 million in 2013.
Trump's top inaugural donor was Las Vegas gambling billionaire Sheldon Adelson, who gave $5 million.
Two other casino moguls were also generous: Phil Ruffin donated $1 million, and Steve Wynn gave $729,000.
The $7.25 million donated to the inauguration by National Football League franchise owners represented about 6.7 percent of all money contributed to the inaugural committee.
Numerous companies that donated to Mr Trump, a Republican, have significant matters pending before the U.S. government or have been invited to White House events.
Numerous companies which made donations to the 2017 event also donated to Obama's prior inauguration.
Trump plans to name the New York Jets' Woody Johnson, one of those million-dollar donors, to be the country's ambassador to the United Kingdom.
Officials with Trump's committee said they will donate still-to-be-determined leftover funds to charities that will announced at a later date.
Billionaire Texan Kelcy Warren, whose company is building the Dakota Access Pipeline, gave the inaugural committee $250,000.
Additional $1 million contributors from the energy sector include a trust tied to billionaire coal operator Joseph Craft and John Hess, the chief executive of the Hess Corp., an oil and gas exploration and production company. Companies also gave big in-kind contributions of goods and services, including almost $500,000 in "vehicle expenses" from General Motors. The Republican National Committee refused a contribution from the US citizen in 2000, citing news reports at the time that cautioned about his ties to Russian business.
Boeing, which gave $1 million, was a strong supporter of the Export-Import Bank, which Trump attacked on the campaign trail but recently praised and nominated former Rep. Scott Garrett (R-5th Dist.) as its president.
President Donald Trump delivers his inaugural address after being sworn in as the 45th president of the United States during the 58th Presidential Inauguration at the U.S. Capitol in Washington on January 20, 2017.
In all, more than 45 individuals and companies donated at least $1 million each to the effort as Trump broke with the practice of most recent inaugural committees and placed no limits on corporate or individual donors. Kerrigan said the inaugural events may have served as an opportunity for donors who held back during the presidential campaign to try to curry favor by showing support for the incoming president. Obama limited contributions to $50,000 in 2009 but lifted that cap four years later. AT&T donated $4.6 million to the 2013 Obama inauguration, according to OpenSecrets.
