Top White House adviser Kellyanne Conway on Thursday gave an on-air shout-out to Ivanka Trump’s clothing line, urging people to buy her merchandise.

“Go buy Ivanka’s stuff, is what I would tell you. … I’m going to give it a free commercial here: Go buy it today,” Conway said on Fox News’ “Fox and Friends.”

The sales pitch prompted Rep. Elijah Cummings to ask the House Committee on Oversight and Government Reform to look into disciplining Conway for possible ethical violations.

“This appears to be a textbook violation of government ethics laws and regulations enacted to prevent the abuse of an employee’s government position,” Cummings (D-Md.) said.

The product placement also led a watchdog group to file a complaint against her.

“The law is clear that public officials should not use their offices for their own private gain or the private gain of others,” Citizens for Responsibility and Ethics in Washington executive director Noah Bookbinder said in a statement. “It’s hard to find a clear case of that kind of misuse of office than we saw today.”

She was defending President Trump, who tweeted on Wednesday about Nordstrom dropping his daughter’s clothing and accessory line.

“My daughter Ivanka has been treated so unfairly by @Nordstrom. She is a great person – always pushing me to do the right thing! Terrible!” Trump wrote.

Conway said Ivanka Trump is a successful businesswoman who is coming under attack by those who disagree with her father’s policies.

They are “using her, who’s been a champion for women empowerment, women in the workplace, to get to him. I think people can see through that,” she said.

Nordstrom said it decided not to sell her line because of declining sales.
