First Lady Michelle Obama will be joined at Tuesday's State of the Union address by the mother and father of Hadiya Pendleton, the 15-year-old Chicago teen who was gunned down in her neighborhood last month shortly after performing at President Barack Obama's inauguration ceremony.

According to NBC News, White House aides said Cleopatra Pendleton had confirmed an invite from the First Lady, who was in Chicago over the weekend to attend the teenager's funeral. Her father, Nathaniel Pendleton Sr., later told DNAinfo that he'd also be in attendance.

Pendleton had earlier been invited to the State of the Union address as a guest of Rep. Brad Schneider (D-Ill.), and was already expected to be in Washington, D.C. with her husband on Tuesday, after a request from Sen. Dick Durbin (D-Ill.) to have them present at a Senate hearing on gun safety. Durbin had spoken of the younger Pendleton's death at a previous Senate hearing.

The president is expected to invoke his campaign against gun violence during his upcoming State of the Union address. Organizing for Action officials recently said they would follow up on his push with a "national day of action" focused on anti-gun violence initiatives on Feb. 22.

Obama will continue to press the issue later this week, when he travels to his hometown of Chicago on Friday to expand on the themes he brings up in his speech on Tuesday. Lynn Sweet of the Chicago Sun-Times reports that he'll talk about the epidemic of gun violence in the city, where more than 500 people were gunned down in 2012.

This post has been updated to include additional information about Pendleton's father attending the address.

  • Justice Alito Mouths 'Not True'

    During the 2010 State of the Union, Supreme Court Justice Samuel Alito mouthed the words <a href="http://www.huffingtonpost.com/2010/01/27/alito-not-true_n_439672.html" target="_hplink">"not true,"</a> in response to President Barack Obama's statement that the Court's ruling in the <em>Citizens United</em> case had "open[ed] the floodgates for special interests -- including foreign corporations -- to spend without limit in our elections."

  • Attendees Caught Sleeping?

    After President George W. Bush's address in 2007, many outlets reported that Sen. John McCain (R-Ariz.) had fallen asleep. However, as <em>The New York Times</em> <a href="http://thelede.blogs.nytimes.com/2007/01/24/state-of-the-union-lullaby/" target="_hplink">pointed out</a>, McCain was likely reading a copy of the speech and just appeared to be dozing off. During the 2010 address, Secretary of Homeland Security Janet Napolitano was also <a href="http://www.huffingtonpost.com/2010/01/27/democrats-asleep-reid-napolitano-sotu_n_439717.html" target="_hplink">caught</a> looking like she was taking a nap, while Senate Majority Leader Harry Reid (D-Nev.) was spotted <a href="http://www.youtube.com/watch?v=rgpwViyAlxo&feature=player_embedded" target="_hplink">yawning</a> while his colleagues applauded President Obama's remarks.

  • Bush Criticized For Using Term 'Democrat Majority'

    In his <a href="http://www.c-spanarchives.org/program/196277-2" target="_hplink">2007 address</a>, President Bush began his speech on a bipartisan foot by commending new Speaker of the House Nancy Pelosi (D-Calif.), saying "I congratulate the Democrat majority." By eliminating the syllable "-ic" from the word "Democratic," Bush caused <a href="http://www.washingtonpost.com/wp-dyn/content/article/2007/01/24/AR2007012402469.html" target="_hplink">a stir</a> among liberals. The phrase "Democrat party" has long been an epithet used by Republicans to express contempt for their opponents. However, it's unclear whether the omission was intentional. The text of Bush's speech said "Democratic party," suggesting that the use of the term was accidental.

  • Democrats Boo President Bush

    After Bush claimed in his 2005 address that Social Security will be "exhausted and bankrupt" by 2042, Democratic members of Congress booed and heckled the president. Many pundits called an "unprecedented" reaction. However, as Media Matters <a href="pointed out" target="_hplink">pointed out</a>, Republicans had similarly booed President Bill Clinton during previous State of the Union addresses.

  • Bush Coins 'Axis Of Evil'

    In his <a href="http://www.washingtonpost.com/wp-srv/onpolitics/transcripts/sou012902.htm" target="_hplink">2002 address</a>, President Bush highlighted the threats posed by North Korea, Iran and Iraq. "States like these, and their terrorist allies, constitute an axis of evil, arming to threaten the peace of the world," he said.

  • Clinton Replaces 'Livable' With 'Liberal'

    President Clinton made a Freudian slip during <a href="http://clinton4.nara.gov/WH/SOTU00/sotu-text.html" target="_hplink">his final State of the Union address</a> in 2000, twice replacing the word "livable" with the word "liberal," and then abruptly correcting himself: <blockquote> Last year, the Vice President launched a new effort to make communities more liberal -- livable -- (laughter) -- liberal, I know. (Laughter and applause.) Wait a minute, I've got a punchline now. That's this year's agenda; last year was livable, right? (Laughter.) That's what Senator Lott is going to say in the commentary afterwards. (Laughter.) To make our communities more livable. This is big business. This is a big issue. What does that mean? You ask anybody that lives in an unlivable community, and they'll tell you. They want their kids to grow up next to parks, not parking lots; the parents don't have to spend all their time stalled in traffic when they could be home with their children. Tonight, I ask you to support new funding for the following things, to make American communities for liberal -- livable. (Laughter and applause.) I've done pretty well with this speech, but I can't say that. (Applause.)</blockquote>

  • Clinton Bypasses Impeachment Troubles

    Despite being in the middle of his trial, Bill Clinton made no explicit mention of impeachment during the 1999 State of the Union. The closest he came was alluding to his troubles: "Yet perhaps in the daily press of events, in the clash of controversy, we do not see our own time for what it truly is: a new dawn for America."

"For our friends in the press who place a high premium on accuracy, let me say, I did not actually hear George Washington say that." </blockquote>
