MSNBC's Joe Scarborough said early Thursday that Democratic leaders must condemn what he called "very offensive" anti-Semitic remarks made by Rep.

"It’s very offensive," Scarborough said on "Morning Joe." "And unless this party wants to dissolve into the left-leaning version of the party of Steve Kings and the party of David Dukes, they need to call her out any time this anti-Semitic trope is trotted out."
"And if that means condemning those statements every day, they should," the host concluded.
The perspective from the former GOP congressman comes ahead of an expected vote Thursday in the Democratic-controlled House on a resolution to broadly condemn hate following Omar's recent pointed criticism of Israel.
The resolution was initially expected to condemn anti-Semitism, but has since been expanded to include Islamophobia and other forms of hate.
Last week, the first-term congresswoman said she wanted to talk “about the political influence in this country that says it is OK for people to push for allegiance to a foreign country," referring to Israel.
Both Republicans and Democrats have condemned those and other remarks by Omar.
Scarborough's reference to King comes after a January interview in The New York Times in which the congressman questioned how terms such as "white supremacist" became offensive.
“White nationalist, white supremacist, Western civilization — how did that language become offensive?” King asked. “Why did I sit in classes teaching me about the merits of our history and our civilization?”
Duke, meanwhile, was the founder of a Louisiana branch of the Ku Klux Klan in the mid-1970s and served as grand wizard of the Knights of the Ku Klux Klan until 1979.
