President Obama's health care overhaul probably will cause some Americans to lose their health insurance, the Wall Street Journal reports.

A study from the Deloitte Consulting Company shows one in 10 employers plans to drop their coverage of workers as the federal health care law is implemented in the next few years.

More companies indicated they would do it over a longer period of time.

Last year, another consulting company found that 30 percent of employers would possibly stop offering health insurance after 2014.

The Congressional Budget Office estimates around 7 percent of workers could lose coverage under the law by 2019.
