The chief of staff to Veterans Affairs Secretary David Shulkin altered an email and made false statements so that taxpayers would foot the bill for the secretary’s wife on a luxury, 10-day trip to Europe last summer, according to the agency’s inspector general. Vivieca Wright Simpson, the VA’s third-most senior official, doctored language in an email from another aide who was planning the trip to make it look like Shulkin was getting an award from the Danish government.
