Washington (CNN) GOP Rep. Mike Coffman of Colorado called for the resignation of Veteran Affairs Secretary David Shulkin Wednesday after the VA's inspector general released the results of an investigation into Shulkin's taxpayer-funded trip to Europe.

"It's exactly corruption and abuses like this that doesn't help our veterans. @SecShulkin must RESIGN now. @realDonaldTrump ran on accountability, it starts here," tweeted Coffman, who sits on the House Veterans' Affairs Committee.

The tweet follows an inspector general's report that said the chief of staff for Shulkin altered an email and made false statements to a department ethics official that led to taxpayers covering expenses for Shulkin's wife on an official trip to Europe last summer.

Vivieca Wright Simpson, Shulkin's chief of staff, altered language in an email regarding the logistics of the trip that led to the department paying $4,312 in airfare for Shulkin's wife, Merle Bari, according to the report.

In a response to VA's Inspector General Michael Missal dated February 12, 2018, Shulkin called the portrayal of the trip "overall and entirely inaccurate."
