The White House was forced to delete and reissue a video that attacked the inaccuracy of the Congressional Budget Office after it misspelled "inaccurately".
The short video, issued by the White House, was released onto its YouTube channel. It attacked the CBO for how they calculate the numbers of people who are covered by health insurance.
In one part of the film, the words read: "CBO inaccurately estimates health coverage."
Followed by: "CBO innaccurately [sic] estimated 25 million would be covered under Obamacare."
The video was quickly deleted and reposted with the correct spelling after people on Twitter spotted the mistake.
CBO ratings are usually relied upon when creating new bills. The current plans to repeal and replace Obamacare are being tested heavily against CBO scores before senators decide to back it or not.
The video claims that the CBO predicted 25m people would be covered by Obamacare in 2017. According to the White House the actual figure is just over 10m.
The video accuses the CBO of using "faulty assumptions and bad numbers".
Republican Senator Susan Collins said: "I'm very concerned about the cost of insurance for older people with serious chronic illnesses and the impact of the Medicaid cuts on our state governments; the most vulnerable people in our society."
There is concern among some Republican senators that if constituents are left uninsured under the new plans, they could be hit at the 2018 mid-terms elections.
Former CBO director Doug Holtz-Eakin added that this kind of attack on the CBO is, if not unprecedented, "extremely rare".
"It just doesn't happen," he said. "The people I worked for in the White House would never have done this."
