"The most excitement in the White House briefing room in months. Reporters attempt to capture a baby mouse that fell on @PeterAlexander⁩ lap moments ago," NBC reporter Shannon Pettypiece tweeted.

The mouse incident came after several months of the White House refusing to hold press briefings, citing the reporters' own behavior at the events.
