yes the error is that cruz and rubio did not confirm info before assuming accurate and forwarding. slice it how ever you want they were wrong to assume and to not confirm with Ben or others that would know, not simply a mistake. At there level of political play they know better.
True, they should have confirmed. I guess they figured that since it was being reported, it was solid.
As I recall from reports at the time, efforts were made to contact Carson’s people, but they were unsuccessful.
They simply made a mistake — repeated a mistake, actually.
To say they lied is as valid as saying that Bush lied us into the war in Iraq.
There is a difference.
