The U.S. government will end its contract with CGI Federal for the error-plagued Obamacare enrollment website HealthCare.gov, instead signing a contract with Accenture, the Washington Post reported Friday in its online edition. U.S.-listed shares of CGI Group, the parent of CGI Federal, were down 3.5 percent at $31.36 in late trading on the New York Stock Exchange. HealthCare.govs technology failures in the weeks after its October 1 launch created a political crisis for President Barack Obama, threatening the rollout of his signature healthcare law to consumers and emboldening its foes among Republican lawmakers to call for its delay. But the governments dissatisfaction over the websites early crash, as well as aspects of the site that still do not work, are behind plans to sign a one-year contract with Accenture instead, the Post report said, quoting a person familiar with the matter.
