Update 12:55 p.m. | Rep. Alan Grayson's campaign reacted quickly Friday to Democratic Senate primary opponent Rep. Patrick Murphy's comparison of him to Donald Trump, pointing out that Murphy's father's construction company had built two major projects for the real estate mogul who's leading Republican presidential polls.
"Murphy's family construction business — where he used to work, where his daddy's money comes from, and in which he owns a share worth $1 million to $5 million — has a business relationship with Donald Trump. How much money has Donald Trump put in Patrick Murphy's pocket?" Grayson adviser Kevin Franck replied in an email to CQ Roll Call.
