White House press secretary Sarah Sanders said Wednesday that House Minority Leader Nancy Pelosi is a symbol of Democrats' bitterness toward President Trump, and said Democrats would be better off if she smiled sometimes.

She was reacting to a question on CNN about Pelosi's dour reaction to Trump's State of the Union address, during which she was mostly unresponsive.

"I think Nancy Pelosi looks like that all the time," Sanders said on CNN. "I think she should smile a lot more often, I think the country would be better for it."

"She seems to kind of embody the bitterness that belongs in the Democrat Party right now," Sanders added.

Sanders also said Pelosi and Democrats have to make a "big decision" about whether they will continue to let their hatred of Trump get in the way of getting things done.

"They need to decide ... do they love America more than they hate this president, and are they willing to put some of those differences aside, come together and do what's right for this country?" she asked.
