Democrats want to counter a recent Supreme Court ruling that makes it harder for older workers to prove they are the victims of age discrimination.

The Senate Judiciary Committee is hearing testimony Wednesday on a bill that would effectively nullify a high court decision that changed the interpretation of age bias laws.

The high court said it is not enough for employees to show age is a motivating factor in a demotion or layoff. Rather, workers must prove it is the deciding factor.

Senate Judiciary Committee Chairman Patrick Leahy says that sets the bar too high for discrimination victims.

The plaintiff in the case was invited to testify. He's Jack Gross, who was employed by an insurance company in West Des Moines, Iowa.
