Reid’s statement is the latest in the growing chorus of criticism leveled at the GOP presidential nominee for his comments about the parents of a Muslim American soldier killed in Iraq.

But instead of focusing his ire solely on the nominee or the heroism of Capt. Humayun Khan, who was killed 12 years ago in Iraq, Reid pushed blamed onto the Republican leaders, who both released statements Sunday praising the Khan family without mentioning Trump.

“Senator McConnell and Speaker Ryan approvingly spoke at Donald Trump’s convention, endorsed Donald Trump for president and believe he is mentally fit to sit in the Oval Office. Occasional statements that do nothing to repudiate Donald Trump’s words and actions are spineless. Anything short of revoking their endorsements is cowardice,” Reid said.

“This shouldn’t be hard. Donald Trump is a sexist and racist man who insults Gold Star parents, stokes fear of Muslims and sows hatred of Latinos. He should not be president and Republican leaders have a moral responsibility to say so‎.”

Trump sparked controversy late last week when he lashed out at Khizr Khan over his speech at the Democratic National Convention, which was critical of Trump. The billionaire doubted whether Khan prepared his remarks and questioned his wife’s silence on stage.

Following the backlash, Trump in a statement late Saturday called Humayun Khan a "hero" but continued to criticize Khizr Khan.
