Update at 1:40 p.m. ET. White House Backs Down:
"We should have sent someone with a higher profile," White House Press Secretary Josh Earnest said during a briefing Monday.
The admission came a day after criticism surfaced over the fact that the United States was not represented by a high-ranking official at a unity rally in Paris. The British, German, Israeli and Palestinian leaders all had been present.
Earnest said, however, that President Obama would have liked to have been present, but the security situation would have been impossible.
