The father of a Muslim U.S. Army captain killed by a suicide bomber in Iraq says he appreciates that Donald Trump called his son a hero, but says he finds the Republican presidential nominee disingenuous because of his policies and his rhetoric.

Speaking on NBC's "Meet the Press," Khizr Khan says Trump showed disrespect toward his wife and that the country needs to be run by someone with a "moral compass."

Khan addressed the Democratic National Convention last week as his wife, Ghazala, stood quietly by his side.

Trump's comments that maybe she wasn't allowed to speak sparked backlash. On Saturday, Trump called their son, U.S. Capt. Humayun Khan, a hero but said the issue was about terrorism and the ability of leaders of the current administration to eradicate it.

Retired Gen. John Allen says Republican presidential candidate Donald Trump has "no credibility" to criticize him about the U.S. battle against Islamic State militants.

Last week, Trump called Allen a "failed general," saying he hadn't done so well in fighting IS.

Allen is a former commander of U.S. and NATO forces in Afghanistan and also was the president's former special envoy for the global coalition to counter IS. In that job, he worked to assemble a group of nations to counter Islamic State militants.

Allen says he doesn't think he has to justify himself to Trump, who has never spent time in Afghanistan or Iraq and has never served in the military.

Republican presidential candidate Donald Trump is suggesting the U.S. accept Russia's annexation of Crimea if it would lead to better relations with Moscow and stronger cooperation in fighting Islamic State militants.

In an interview broadcast Sunday on ABC's "This Week," Trump suggested that the people of Crimea would rather be part of Russia. That runs counter to the Obama administration, which imposed economic sanctions against Russia for annexing the territory in Ukraine two years ago.

The United Nations doesn't want countries to recognize Crimea as part of Russia, and some top Republicans are staunchly defending Crimea against what they say is Russian aggression.
