(TMZ) - Justin Timberlake rarely makes political commentary, but he made an exception with a TMZ camera guy Thursday night ... when the paparazzi brought up President Trump.

He was leaving ArcLight in Hollywood when TMZ asked about Trump's bombastic Thursday news conference where he attacked the media on all sorts of fronts. Justin's response was brief, but he said a lot. 

Not that it's entirely shocking -- he and Jessica Biel hosted an HRC fundraiser last year. Sorry, JT ... no refunds.
