During a visit to the Iowa State Fair on Saturday, Republican presidential candidate Donald Trump -- while repeatedly describing her as “nice woman” -- took aim at his GOP rival, former Hewlett-Packard CEO Carly Fiorina, attacking her record in the private sector and her failed California Senate bid. “She's a very nice woman, she got fired, she did a terrible job at Hewlett-Packard, she lost in a landslide -- other than that, she's a very nice woman,” Trump, echoing recent comments, told ABC News Martha Raddatz when asked for his thoughts on his solo female GOP competitor for the nomination.
