(AP) -- The Missouri House has endorsed legislation that would change the state's workplace discrimination laws.

House members gave first-round approval Tuesday to legislation that would require workers who fight firings or other adverse decisions to prove in court that discrimination was a "motivating factor" -- and not just a contributing factor. It needs another vote before moving to the Senate.

The legislation was approved 84-70. That is just barely over the 82 votes needed to pass legislation through the House.

Senators backed similar legislation last week after an all-day debate.

Democratic Gov. Jay Nixon vetoed an employment discrimination bill last year.
