Report: Trump could spend more on travel in 1 year than Obama did in 8 years

President Donald Trump's frequent visits to his Mar-a-Lago estate in Florida in the past three months have already cost U.S. taxpayers around $20 million, CNN reports.

If Trump continues to treat his resort as a second White House, his total travel expenses in a single year could surpass those of Barack Obama during his entire eight years as president, according to CNN.

This might be surprising to some since Trump was quick to criticize Obama for spending taxpayers' dollars on travel during his presidency.

We pay for Obama's travel so he can fundraise millions so Democrats can run on lies. Then we pay for his golf. — Donald J. Trump (@realDonaldTrump) October 14, 2014

Trump spent 21 days of the first 80 days of his presidency at Mar-a-Lago, his members-only club in Palm Beach, Fl. He has retreated to the resort on many weekends and also used it as a place to host world leaders including Japanese Prime Minister Shinzo Abe and Chinese President Xi Jinping.

Even before this week's summit, Trump and his aides had begun referring to Mar-a-Lago as the "Winter White House," a marketing coup for a man who has made millions selling his personal brand. Now the president is writing his property deeper into American history books by meeting there with China's Xi Jinping. less In this March 4, 2017 file photo, President Donald Trump waves to his supporters as the presidential motorcade passes through Bingham Island on the way to Mar-a-lago in Palm Beach, Fla.

To calculate the total cost of these trips, CNN used a 2016 Government Accountability Office report for a four-day trip Obama took to Florida in 2013. The trip cost $3.6 million with the bulk of the money going toward security.

CNN put Trump's total Mar-a-Lago costs for travel and security at $21.6 million. (The BBC has the amount at $23 million.)

By comparison, Obama's travel tab was nearly $97 million during his entire presidency, according a to a 2016 report from Conservative Watchdog Group Judicial Watch. The group's report includes his travel expenses for pleasure (Hawaii family vacation), work (Earth Day speech at Everglades National Park in Florida) and fund-raising (a 2015 San Diego trip).

If Trump continues at his current rate, he'll likely spend exponentially more than Obama on travel. The Huffington Post postulates that if he were to serve an eight-year term, his travel expenses "would add up to close to $800 million."

SFGATE reached out to the White House media department for comment on Trump's travel expenses and didn't hear back before publishing the story.
