U.N. Ambassador Nikki Haley urged Americans in a tweet to "stop the blame" following the massacre at a Pittsburgh synagogue over the weekend.

Haley, who earlier this month offered her surprising resignation, tweeted that she's "struggled" with what happened at the Tree of Life Synagogue due to its similarities with the 2015 church shooting in Charleston, South Carolina.

Haley served as the governor of South Carolina from 2011 to 2017 until accepting her position at the United Nations.

She said that Americans "didn't once blame Pres. [Barack] Obama" following the Charleston shooting and focused only on the lives lost.

Fox News contributor Mollie Hemingway said Tuesday on The Story that it has been "disappointing" to see some on the left use the Pittsburgh shooting as a "political cudgel."

She said that during Obama's presidency, he was largely commended for his work during trying times such as the Charleston shooting.

"That is a much better way to be," Hemingway said.

She added that the recent anti-Semitic rhetoric is a "universal problem," and one that shouldn't be used to target one political party.
