Romney weighs in on Elizabeth Warren’s campaign promises

Republican Senator Mitt Romney is weighing in on the key platform in Elizabeth Warren's presidential campaign.

On Twitter, Romney criticizes the Democratic senator's Medicare For All proposal. 

In the post, he cites other countries with a socialized medicine system, stating they "make their numbers work through limits on care, cost sharing, and higher middle class taxes."

Romney ends by calling Warren's plan "inauthentic and disingenuous."
