Directors Daniel DiMauro and Morgan Pehme, who made “Get Me Roger Stone,” have a way of insinuating themselves into the right. Their latest film  “The Swamp” (HBO 9 p.m.) takes a close look at another off-putting character, Rep. Matt Gaetz of Florida, who sleeps in his office and thinks up moments that would go viral. 

The shaky premise here is that he’s a “maverick Republican” who occasionally sides with Democrats to buck the block of lobbyists. More admirable in this cause is Thomas Massie of Kentucky, who avoids the constant fundraising. An interesting look inside anyway. 

Higher standards overall can be found in “John Lewis: Celebrating a Hero” (CBS, 10 p.m.) which recounts the life of the Congressman and Civil Rights hero with the participation of Oprah Winfrey, Tyler Perry, Gayle King, Brad Pitt, Common, John Legend, Trevor Noah, Billy Porter and Jennifer Hudson, among others. 

Much less celebrating of Lewis is found in Jonathan Swan’s eye-opening interview with Donald Trump on “Axios” (HBO2, 10:45 p.m.), which deserves your attention.

Elsewhere, there’s a sequel in the teen lifeguard series “Malibu Rescue: The Next Wave” (Netflix, streaming) in which they must compete as Team USA against accomplished international teams. 

A “Saturday Night Live” writer gets her own standup comedy special “Sam Jay: 3 in the Morning” (Netflix, streaming), shot in Atlanta. 

In the new series “What’s It Worth?” (A&E, 9 and 9:30 p.m.), Jeff Foxworthy asks people to share their collectibles. He visits them virtually.

It joins another new show with similar restrictions: “Extreme Unboxing” (A&E, 10 and 10:30 p.m.), in which enterprising people who might have competed on “Storage Wars,” buy big boxes of returned merchandise from online merchants.
