Feuds with Lawrence O'Donnell: "His show is unwatchable"

Trump engaged in a Twitter feud with MSNBC host Lawrence O'Donnell, calling his show "unwatchable" and claiming O'Donnell made "many false statements" about him. The spat highlighted Trump's thin skin regarding media criticism and his willingness to punch down at cable news hosts, a precursor to his presidency's war on the press.
