yeah, I was just looking at the moment when that happens, and it's clear he is agreeing with someone who quips something.
POTUS: In less than two years my administration has accomplished more than almost any administration in the history of our country. America's–
AUDIENCE MEMBER: (inaudible)
[speculation: something like: "Especially recently!" "Wouldn't be tough!" "Combined!" - or something to that effect.]
POTUS: So true!
AUDIENCE: laughter from agreement (any smart alec comments would have made the audience uncomfortable or some would have cheered if they don't like POTUS etc. Laughter of agreement sounds more plausible).
POTUS: (laughs) Didn't expect that reaction, but that's okay!
MOAR AUDIENCE LAUGHTER (again sounds like the kind from agreement)
APPLAUSE (from the levity of a great moment, in appreciation of POTUS and his good humor)
MSM narrative: "Audience laughs at POTUS who makes a "grandiose claim."" - You mean a TRUE claim, with which the audience agreed.
