Republican Sen. Mitt Romney of Utah is stressing that the country’s politics has “moved away from the spirited debate to a vile, vituperative, hate-filled morass that is unbecoming of any free nation.” And the 2012 GOP presidential nominee warns that the "rabid attacks kindle the conspiracy mongers and the haters" to launch "dangerous action” such as the recent kidnapping plot against Michigan Gov. Gretchen Whitmer. Romney, the most vocal Republican critic of President Trump in Congress, took to Twitter on Tuesday to take aim at the president.
