Ted Cruz Fires Top Aide for Spreading Misinformation on Marco Rubio

Mr. Cruz went on to call Mr. Tyler a “good man,” but that his sharing of the story was “a grave error in judgment.”

.. The firing represents a public admission of what Mr. Rubio and his aides have angrily claimed for weeks: that the Cruz campaign is undertaking unfair and deceitful tactics to undermine rivals, such as a using manipulated photograph, doctored by Cruz aides, that suggested Mr. Rubio had shaken hands with President Obama in front of the Capitol in Washington.
