Two days before he is sworn into the United States Senate, incoming Utah Senator Mitt Romney is blasting President Donald Trump’s character.

“On balance, his conduct over the past two years, particularly his actions this month, is evidence that the president has not risen to the mantle of the office,” Romney wrote.

The senator stated that he had confidence that Trump would succeed early in the presidency as he appointed Rex Tillerson, Jeff Sessions, Nikki Haley, Gary Cohn, H.R. McMaster, John Kelly and Jim Mattis to positions in his administration.

None of the names Romney listed are still working for Trump, with Mattis, Kelly, and Haley all leaving their posts in December 2018. Haley announced her departure in October, while Mattis and Kelly left last month.

Romney mentions that Trump has established some good policies for America, including the appointment of conservative judges, cracking down on China’s trade practices and criminal justice reform.

“These are policies mainstream Republicans have promoted for years. But policies and appointments are only a part of a presidency,” Romney said.

Romney writes that America has been looked to across the world for leadership and at a time when many European allies are experiencing “political upheaval” that leadership is more important than ever.

“Trump’s words and actions have caused dismay around the world. In a 2016 Pew Research Center poll, 84 percent of people in Germany, Britain, France, Canada and Sweden believed the American president would “do the right thing in world affairs.” One year later, that number had fallen to 16 percent,” Romney said.

“The world needs American leadership, and it is in America’s interest to provide it. A world led by authoritarian regimes is a world — and an America — with less prosperity, less freedom, less peace.”

Romney frequently criticized Trump in the run-up to the 2016 election, and has remained vocal about his discontent with some of the president’s behavior and policies since Trump entered the White House.

In response to the op-ed, Trump’s 2020 campaign manager Brad Parscale responded on Twitter, writing, “The truth is @MittRomney lacked the ability to save this nation. @realDonaldTrump has saved it. Jealously is a drink best served warm and Romney just proved it. So sad, I wish everyone had the courage @realDonaldTrump had.”

Romney served as the governor of Massachusetts from 2003 to 2007 and was the Republican nominee for president in 2012.
