WASHINGTON (Reuters) – Six Democratic U.S. senators on Thursday asked Walmart Inc, Walgreens Boots Alliance Inc, Rite Aid Corp and Dollar General Corp to stop selling all tobacco products.

The senators cited the “public health crises” of use of e-cigarette products by children and the recent outbreak of vaping related illnesses and deaths.
