On Friday’s weekly PBS journalist roundtable Washington Week with The Atlantic, panel regular Susan Glasser of the New Yorker foisted insults on President Trump for being obliged to appear at the State of the Union after losing on tariffs at the Supreme Court, “I really think that this is a really embarrassing political moment for Donald Trump to be going up to Capitol Hill for the State of the Union.” After that outburst, the panel turned to the upcoming Tuesday address. PBS’s congressional correspondent Lisa Desjardins found something to watch out for: Heckling of the president (though many Democrats have vowed to stay away from the address in protest). Lisa Desjardins: ….I think I can confidently say there's a hope by most members of Congress, Republican, and Democratic leaders, that there won't be the kind of yelling that you see. They -- both sides have something to lose by that. However, there's a question about Democratic progressives. They're having an alternate event. Some of them are skipping the State of the Union all together, but some will attend. Leader Jeffries, I've been told by many Democrats, is asking Democrats to just be respectful. But he has many progressives who are seething and who -- it's going to be hard for them to not yell when he says something they see as a lie. Desjardins seemed copacetic about the prospect of Trump being shouted at by Democrats. Needless to say, that kind of empathy regarding the frustrations of the party in opposition was not how the PBS News Hour reporters reacted when President Obama was confronted by Rep. Joe Wilson (R-SC) during a 2009 speech on his health care proposal (later known as Obamacare) to a joint session of Congress. Coverage on the September 10, 2009 PBS News Hour reproved Wilson, and the brief incident became a multi-day story. Reporter Kwame Holman: Attention to the president`s plan and the debate over it were diverted somewhat today by some of the reaction last night during his address to Congress. A Republican from South Carolina created a furor when he heckled Mr. Obama. Congressman Joe Wilson shouted out, "You lie!" when the president said his plan would not include insuring illegal immigrants. Barack Obama, President of the United States: The reforms -- the reforms I`m proposing would not apply to those who are here illegally. Rep. Joe Wilson (R-SC): You lie! Holman: This morning, Wilson went before reporters staked out at his office and apologized. Days later, on Sept 14, then-News Hour anchor Gwen Ifill scolded that “Rancor had become the hallmark of Washington debate, so much so that even the president weighed in on the matter on 60 Minutes last night.” Barack Obama, President of the United States: The truth of the matter is that there has been a coarsening of our political dialogue that I've been running against since I got into politics…. Ifill: Last week`s primetime example occurred during the president`s address to a joint session of Congress. President Obama: The reforms -- the reforms I`m proposing would not apply to those who are here illegally. Rep. Wilson: You lie! And again the next night: Ifill: The U.S. House of Representatives passed a resolution of disapproval today against Republican Joe Wilson. Last week, the South Carolina congressman touched off a furor when he shouted, "You lie!" during President Obama`s health care speech to a joint session of Congress. Wilson later apologized to the president`s chief of staff, but he refused Democrats` demands to apologize to colleagues on the House floor. That, in turn, triggered today`s debate. If Democrats were to heckle President Trump on Tuesday night, will PBS’s reaction be equally extended and judgmental?
