Sen. Romney cautions against divisiveness in farewell speech

What they're saying: "I've been in public service for 25 years," Romney said. "I have learned that politics alone cannot measure up to the challenges we face."

• "A country's character is a reflection not just of its elected officials, but also of its people. I leave Washington to return to be one among them, and hope to be a voice of unity and virtue."

What we're watching: Sen.-elect John Curtis, who currently represents Utah's 3rd Congressional District in the House, will replace Romney next month after winning his election bid in November.

• Curtis, also widely considered a moderate Republican, has been described as "less willing to fall in line with Trump's whims," Axios' Stef Kight reports.
