Donald Trump. Joe Raedle/Getty Images Donald Trump's recent feud with a Gold Star family was significantly damaging to his campaign, according to two polls released on Wednesday.

A poll from Fox News found that 69% of respondents familiar with Trump's recent criticism of the Khan family said that his remarks were "out of bounds."

Among Republicans, 41% said that it was "out of bounds."

The Khans, whose son, Capt. Humayun Khan, was killed during the Iraq War in 2004, denounced Trump during a speech at the Democratic National Convention in Philadelphia on Thursday.

Trump then spent days after the address lobbing various criticisms at the family while noting that their son was a hero.

Elsewhere, a Wednesday Morning Consult poll showed that 34% of registered voters were less likely to vote for Trump as a result of the feud. That number was 53% among Democrats, 31% among independents, and 14% among Republicans. Just 14% of respondents said that the feud made them more likely to vote for Trump.
