WASHINGTON - President Donald Trump on Monday endorsed former Republican presidential candidate Mitt Romney's run for a US Senate seat in Utah despite Romney often being critical of Trump. During the 2016 presidential campaign, Romney excoriated Trump as a 'fraud' who was 'playing the American public for suckers.” Trump responded that Romney had 'choked like a dog' in his 2012 campaign against President Barack Obama. Trump said on Twitter that Romney 'will make a great Senator and worthy successor to @OrrinHatch, and has my full support and endorsement!' Romney announced Friday he would run to replace retiring Senator Orrin Hatch.
