The revelation that the US housing secretary, Ben Carson, and his wife\u00a0selected\u00a0a $31,000 dining set for his office at taxpayer expense has caused outrage. But Carson is far from alone among Donald Trump\u2019s cabinet in causing controversy over use of public money. Here are the most high-profile examples.\r\nBen Carson\r\nThe housing and urban development (Hud) secretary had managed to keep his head down, more or less, since being put in charge of the sprawling department that deals with America\u2019s under-funded public housing stock. But things changed for the ex-brain-surgeon last month when it emerged that Hud had agreed to\u00a0spend\u00a0$165,000 on \u201clounge furniture\u201d for its Washington headquarters, in addition to a $31,000\u00a0dining\u00a0set\u00a0selected\u00a0by Carson and his wife for his office.\r\nNews of the expensive decor spending emerged\u00a0after the Guardian revealed\u00a0that a senior Hud employee had complained of facing retaliation after she said the budget broke the law. She said she had been told: \u201c$5,000 will not even buy a decent chair.\u201d The report emerged as the administration was proposing to cut $6.8bn, or 14%, of Hud\u2019s annual budget.\r\nSteve Mnuchin\r\nThe treasury secretary, a former Wall Street executive and Hollywood producer who is worth as much as $35m, managed to\u00a0run up\u00a0bills in excess of $800,000 in his first six months in office for travel on military jets. It\u2019s true that Mnuchin withdrew a\u00a0request\u00a0for a US air force jet for his honeymoon in Scotland, France and Italy, after\u00a0marrying\u00a0the Scottish actor Louise Linton last summer at the Trump International hotel near the White House. But the damage to his reputation was already done \u2013 not least by a\u00a0picture\u00a0of Linton descending from a government plane the couple had taken to Kentucky, where Mnuchin visited Fort Knox and they viewed the solar eclipse.\r\nAfter the trip, Mnuchin\u2019s wife caused a brouhaha when she posted a picture of herself on Instagram exiting the government aircraft with her husband,\u00a0notingher designer clothing and accessories. \u201cGreat #daytrip to #Kentucky!\u201d Linton wrote, listing #rolandmouret, #hermesscarf, #tomford sunnies, #valentino. When a woman from Oregon commented online: \u201cGlad we could pay for your little getaway. #deplorable\u201d, Linton responded: \u201cAw!!! Did you think this was a personal trip?! Adorable! Do you think the US govt paid for our honeymoon or personal travel?! Lololol. Have you given more to the economy than me and my husband? Either as an individual earner in taxes OR in self sacrifice to your country?\u201d\r\nTreasury officials have defended the travel and the department\u2019s inspector general has\u00a0said\u00a0it was within the law.\r\nScott Pruitt\r\nThe environment secretary\u00a0has said he\u00a0has to travel first-class because of threats from members of the public who object to his climate-change-denying, regulation-slashing mission in government. Last summer he\u00a0flew\u00a0first-class on the short hop from Washington to New York for brief media appearances after\u00a0pullingAmerica out of the Paris climate agreement.\r\n\r\n\r\n\r\n\r\n\u00a0\r\n\r\n\r\nBut last week he said he was considering flying in the back of the plane, despite having complained of \u201cunprecedented\u201d threats and \u201cincidents\u201d on planes and in airports after he was appointed. One person yelled: \u201cScott Pruitt, you\u2019re fucking up the environment,\u201d an EPA staffer\u00a0told CNN, although this was apparently at the airport in Atlanta, rather than in a plane.\r\nHe also\u00a0spent\u00a0as much as $43,000 on a soundproof \u201cprivacy booth\u201d inside his office to prevent eavesdropping on his phone calls and $9,000 for biometric locks and to have his office swept for listening devices. Earlier this month it was\u00a0reported\u00a0that he used $6,500 in public money to hire a private media firm with strong Republican ties to help produce a report promoting his accomplishments.\r\nDavid Shulkin\r\nThe secretary of veterans affairs, who joined the department during the Obama administration, is\u00a0reportedly\u00a0wobbling on his perch over complaints that he asked a member of his security detail to accompany him to a branch of Home Depot, the home improvements chain, and then obliged the person to carry his furniture purchases into his home for him.\r\nLast month, the inspector general released a\u00a0blistering report\u00a0finding ethical violations in Shulkin\u2019s trip last July to Denmark and Britain that mixed business with pleasure, including a trip to Wimbledon and a cruise down the Thames.\r\nRyan Zinke\r\nThe interior secretary is from Montana, deep in cowboy country, and is famous for\u00a0riding\u00a0into Washington on his horse Tonto to take up his post. But when he wanted to go riding with the vice-president, Mike Pence, he took a government-funded\u00a0helicopter\u00a0\u2013 one of three such journeys in 2017 that cost a total of $53,000 of public money. In addition, Zinke, who is\u00a0in favor\u00a0of oil, gas, coal and uranium extraction on spectacular public wilderness lands out west, took a charter flight to the US Virgin Islands. He has been\u00a0rebuked\u00a0by the department watchdog for failing to keep proper records of his travel expenses and to show clearly who paid for his wife to accompany him on work trips.\r\nTom PriceThe health and human services secretary was forced to\u00a0resign\u00a0last September following revelations that he used at least $400,000 and probably\u00a0more\u00a0than $1m in taxpayer funds on private and military\u00a0flights\u00a0for himself and his staff. As a Georgia congressman, Price was a fiscal conservative,\u00a0railing\u00a0against the use of private jets by members of Congress. Lawmakers are normally expected to use commercial flights. When Trump\u00a0told\u00a0reporters \u201cI\u2019m not happy, OK?\u201d about Price\u2019s spending, it was the death knell.
