Here is the Breitbart Headline: "Democrats in Congress refused to stand while a Navy SEAL’s widow was acknowledged by President Trump in his speech before a joint session of Congress Tuesday night." They followed this headline with the following accusation: "Sen. Bernie Sanders (I-VT), Sen. Al Franken (D-MN), Rep. Nancy Pelosi (D-CA), and Sen. Patty Murray (D-WA), among others, remained firmly seated and did not applaud at all while the rest of the room gave Carryn Owens a standing ovation, IJR reported."
Notice the weasel phrase, "IJR reported." This is a tactic used by fake news outlets to report a story that they could easily verify or debunk but would prefer not to because the story, as it stands, supports their world view. So instead of reporting it themselves which they could have done, or discrediting it altogether, they merely repeat the unverified story because it hurts - the Democrats.
But of course, the story was false.
Snopes investigated and found the video, on the White House web site that showed Democrats standing and applauding. The fake news outlets used photos of Debbie Wasserman Schultz and Keith Ellison from other unrelated parts of the so-called President's speech to the joint session of Congress.
