Monday night's event marked the first time Melania Trump was seen in public since early May.
After sharing the video, Greene who is part of a Gold Star family, relayed some of the President's comments regarding Melania and her health.
The first lady herself tweeted photographs showing her in the audience.
Melania addressed the rumours about her location on 30 May when she tweeted: "I see the media is working overtime speculating where I am & what I'm doing". "The language and syntax sounded so suspiciously like like a certain social media addict, it only served to fuel the flames", says Vanity Fair. "It's her style and we just have to accept that".
Did they miss the part where the first lady spent five days in the hospital? According to the White House, the first lady returned home on May 19th.
"She's looking at us, right there", he said, gesturing toward the residence.
Nevertheless, CNN's "Reliable Sources" newsletter on Monday led with a giant graphic of a calendar, placing question marks on each date since Mrs. Trump was "last seen" on May 10.
Three weeks ago, a reporter at the White House briefing asked if the First Lady was actually living at the White House.
Even Trump himself got in on the jokes, making mention of the buzz around Melania's disappearance during his speech to the Gold Star families. Then she lowered the boom of criticism that America deserves transparency in the whereabouts of the First Lady.
Probing why Mrs Trump would be a no-show for the marquee meetings, NBC claimed it could be as simple as wanting to avoid post-surgery blood clotting on flights.
