CBS host Margaret Brennan pressured Republican National Committee Chairwoman Ronna McDaniel to address recent criticisms of her uncle, Utah Sen. Mitt Romney.

Romney, 72, has been ripped by some Republicans for criticizing President Trump throughout the impeachment process. On Friday, he and Maine Sen. Susan Collins were the only two Republicans to vote in favor of hearing from additional witnesses in the impeachment trial.

In response to Romney’s wavering support of the president, the American Conservative Union announced that he would not be invited to the CPAC, an annual gathering of conservatives.

On Sunday's Face the Nation, Brennan asked McDaniel, “ President Trump's relationship — he has reshaped the party, but there are still traditional Republicans who aren’t entirely comfortable with everything he does, including, your uncle, Senator Mitt Romney, who voted for witnesses.”

“I disagree that the president’s changed the Republican Party. I think the president strengthened our party,” McDaniel responded.

Brennan continued to push, asking, “I don’t know if you saw that ad, but it was your uncle’s face there. Disinvited or not invited.”

McDaniel replied, “That’s the grassroots part of the party, and they’re upset. They’re upset when people aren’t supporting the president and supporting our party, and they think if you’re not supporting him, you’re helping a Democrat get elected. That’s a very common belief among the grassroots of our party.”

She added, “But I will say, this president’s stood for life, he stood for rule of law judges, he stood for tax cuts, he stood for deregulation, energy independence. These are Republican ideals, and he has made the RNC significantly stronger by supporting our party, and we will be stronger after him because of the investment he’s put into data and digital and the things to make us strong beyond his presidency.

Brennan finished the interview, saying, “I understand. You don’t want to comment on your comfort and your uncle and the comments about him.”

McDaniel, 46, took over as chairwoman for the Republican National Committee in January 2017. Her father, Scott Romney, is Mitt Romney’s older brother.
