WASHINGTON (CBS19 NEWS) -- More than two dozen members of the U.S. Senate, including Tim Kaine, are criticizing a new policy they say won't address certain flavored e-cigarettes or flavored e-liquids that are not in cartridges.

The senators sent a letter to Dr. Stephen Hahn, the new commissioner of the Food and Drug Administration, raising concerns about loopholes for flavors that appeal to children.

In the letter, they criticize the FDA's decision to "break the Trump Administration's promise to clear all non-tobacco flavored e-cigarette products from the market."

They wrote the new policy includes exceptions that affect menthol-flavored products and any flavored e-liquids that are not in cartridges.

"These products have not undergone a scientific review by FDA of their impact on public health," wrote the senators. "Leaving them on the market will place millions of children at risk of addiction. As the newly confirmed FDA Commissioner, you have the opportunity, and the obligation, to take meaningful action to address the ongoing youth vaping crisis. FDA's recently announced compliance policy fails to prioritize children, families and the public health ahead of industry objections."

The FDA policy was announced on Jan. 2, and the senators say it leaves all tobacco- and menthol-flavored electronic nicotine delivery systems, or ENDS, and all flavors of e-liquids for "open tank" ENDS on the market.
