quote:

Julie Bataille from the university's press office e-mailed me that the White House had asked that all university signage and symbols behind the stage in Gaston Hall be covered.

"The White House wanted a simple backdrop of flags and pipe and drape for the speech, consistent with what they've done for other policy speeches," she wrote. "Frankly, the pipe and drape wasn't high enough by itself to fully cover the IHS and cross above the GU seal and it seemed most respectful to have them covered so as not to be seen out of context."
