The standards chief of the US Congress says a senior Trump aide was “wrong, wrong, wrong” to promote Ivanka Trump products on live television.
Kellyanne Conway told Fox News on Thursday: “Go buy Ivanka’s stuff.”
Retailer Nordstrom earlier this month dropped the US first daughter’s clothing line, citing a lack of sales.
The White House said President Donald Trump “absolutely” continued to support Ms Conway, despite intense criticism of her remarks by politicians.
Jason Chaffetz, a Republican who heads the oversight committee in Congress, said the promotion was “clearly over the line, unacceptable”.
