The NEH press release is here. Will President Trump attend? One doubts it!
ADDENDUM: A list of past Jefferson Lecturers--I see only three previous philosophers (Sidney Hook, Leszek Kolakowski, and Stephen Toulmin). Republican Administrations have typically favored humanists with "conservative" reputations--this may be a challenge for Trump, since so many conservative scholars opposed him! (I'd bet money on signatories to this statement being good candidates for Jefferson Lecturer and a National Humanities Medal, at least until Trump's impeachment.)
