Sen. Bill Nelson on Wednesday called for a federal investigation of Lumber Liquidators amid allegations that it sold an imported laminate that could pose health risks.
The Florida Democrat sent a letter to federal agencies asking them to independently test the company's flooring products. He also sought to discover whether the company made potentially false marketing claims about its product's compliance with safety standards.
"Because this could affect millions of homeowners, it's imperative we get some answers quickly," Nelson said in a release.
Shares in Lumber Liquidators were down about 12 percent Wednesday afternoon.
Options trading in the retailer spiked after Nelson's statement, according to Jon Najarian of OptionMonster and a CNBC contributor. More than 20,000 put options in Lumber Liquidators traded in the 40 minutes following Nelson's announcement.
Volume had already surged since the "60 Minutes" report. The three-month average put trade in Lumber Liquidators before it aired was about 3,300 contracts, according to Najarian.
