Political fact checkers in the United States are debunking some of the claims by the three 2016 Democratic presidential contenders at their latest debate.
The Washington Post, The New York Times, Politico and Politifact all said there is no evidence for the claim made Saturday by the party's frontrunner, former Secretary of State Hillary Clinton, that the Islamic State group is showing videos of the leading Republican candidate, billionaire real estate tycoon Donald Trump, "insulting Islam and Muslims in order to recruit more radical jihadists."
The Post said Trump's anti-Muslim rhetoric has been referenced by IS recruiters in social media, but analysts who monitor the jihadist group have not turned up any videos.
"She just made it up," Trump said of the Clinton claim on ABC's "This Week" on Sunday.
Politico also disputed the claims by Clinton that only 3 percent of her campaign donations have come from wealthy people "in the fiance and investment world," saying the figure is about twice that, including money contributed directly to her campaign and an independent group supporting her bid to succeed President Barack Obama when he leaves office in January 2017.
Politico noted that one of Clinton's Democratic opponents, former Maryland Governor Martin O'Malley, was wrong when he cited U.S. difficulties in Iraq and Syria, "where we've involved ourselves in toppling dictators without having any idea what comes next."

Politico said that "is certainly true in Iraq," after the fall of Saddam Hussein, but "quite the opposite in Syria," where President Bashar al-Assad remains in power in the midst of a years-long civil war defending his regime.
The Post questioned the claim by the third candidate seeking the party's presidential nomination, Senator Bernie Sanders of Vermont, that female workers in the United States are paid only 79 cents out of $1 compared to men.
The newspaper said the 21-cent gap is accurate when compared on an annual basis, but that it is less than that when comparing weekly or hourly wages, and comparisons made more difficult by life choices men and women make in the United States, such as women tending to leave the work force when they have children.
U.S. political surveys show Clinton, Obama's top diplomat from 2009 to 2013, with a commanding lead in the race for the Democratic nomination.
The surveys show Trump is outdistancing a large field of Republican candidates, with Texas Senator Ted Cruz and Florida Senator Marco Rubio his closest competitors.
State-by-state nominating contests in both parties start in February.
