Input: Washington (CNN) Donald Trump's travel to his private club in Florida has cost over an estimated $20 million in his first 80 days as president, putting the president on pace in his first year of office to surpass former President Barack Obama's spending on travel for his entire eight years. The outsized spending on travel stands in stark relief to Trump's calls for belt tightening across the federal government and the fact that he regularly criticized Obama for costing the American taxpayer money every time he took a trip. Given variations in each trip, estimating the security costs around a presidential trip is difficult. But a 2016 Government Accountability Office report about a four-day trip Obama took to Florida in 2013 -- one similar to Trump's trips -- found the total cost to the Secret Service and Coast Guard was $3.6 million.Conservatives frequently attacked Obama for spending on his travel while presidentTrump has spent 21 days at his Mar-A-Lago resort in Florida 
 Question:But as much as the trips are a budget problem for _, they are also a public relations issue.
