Example Input: Tampa, Florida (CNN) -- With Texas Gov. Rick Perry threatening to cement his standing atop the national polls, his rivals for the Republican presidential nomination aggressively sought to undermine his conservative credentials on Monday during the first-ever CNN/Tea Party debate in Florida. Perry repeatedly found himself in the crosshairs, as the field of candidates took turns attacking his positions on illegal immigration, Social Security, and his controversial 2007 push to vaccinate Texas schoolgirls against human papillomavirus, a common sexually transmitted disease that can lead to cervical cancer. Minnesota Rep. Michele Bachmann, whose standing among Republicans has slipped dramatically since Perry entered the race, said she was "offended" by Perry's executive order, which included an opt-out provision for parents who did not want the vaccine.NEW: Perry finds himself in the crosshairs as GOP candidates attack his positionsBachmann accuses Perry of helping a drug company through a vaccination orderRomney on Perry: Being dealt aces does not make a good poker playerPerry calls for Social Security reform but drops "Ponzi scheme" label

Example Input: Washington (CNN) The Trump kids aren't alright. As the campaign enters its final stretch, some of Donald Trump's children are showing signs of impatience and struggling to stay on message. In the past 24 hours, Ivanka Trump and Donald Trump Jr. have cut off interviews when pressed for answers on tough questions. Trump Jr. strayed from the campaign's talking point about the Republican nominee's tax returns -- that they'll be released once an IRS audit concludes -- when he said unveiling the documents would "detract" from his father's message. And Trump Jr. caused a firestorm when, during a Thursday interview with a Philadelphia radio station, he raised the specter of the Holocaust by saying if Republicans acted like Hillary Clinton, the media would be "warming up the gas chamber." The campaign later said Trump Jr. was referring to capital punishment, though the Clinton campaign quickly seized on the remarks.Trump's children have increased their appearances on the campaign trail in recent weeksIvanka and Don Jr. both cut off interviews when faced with tough questions
