Rep. Ilhan Omar weighed in on claims that she married her brother while she criticized Rep. Steve King's comments about rape and incest.

"Gross! This would explain why these weirdos are fixed on smearing me with claims of incest," the Minnesota Democrat tweeted Wednesday. "Projecting their filth, unreal."

The Iowa Republican questioned how much of humanity would exist without conception from rape or incest.

"What if we went back through all the family trees and just pulled out anyone who was a product of rape or incest?" King asked. "Would there be any population of the world left if we did that? Considering all the wars and all the rapes and pillages that happened throughout all these different nations, I know that I can't say that I was not a part of a product of that."

House Republicans pulled King, 70, from all his committee assignments in January after he wistfully mused to the New York Times about how white nationalism and white supremacy had become offensive. Omar, 37, praised the decisions, saying King had "no business" being in Congress.

The freshman congresswoman's reference to the accusations that she married her brother follow media investigations into inconsistencies in the congresswoman's alleged marriage history. Several fact checking groups have found the claims made against Omar are inconclusive. A Politifact investigation said there was no "smoking gun" for claims that she married her brother, but there was "circumstantial evidence that begs for some kind of explanation from a member of Congress."

Omar has been reticent to talk about her marital history, refusing on multiple occasions to respond to inquiries by the Washington Examiner and other news outlets. In fall 2018, before she was elected to Congress, she gave her last significant public statement on her marriage history in an interview with the Associated Press.

Omar called the accusations "disgusting lies" and said that she did not want "to further the narrative" by providing any documentation to prove her side of the story.

Accusations against the congresswoman have continued to dog her after the Minnesota Campaign Finance and Public Disclosure Board revealed in June that she broke federal tax law by filing taxes with a man to whom she was not legally married.

A subsequent investigation by the Washington Examiner into dozens of legal documents suggested Omar lived with her first husband while she was married to her second husband. Some critics, including President Trump, have speculated that the second husband might have been her brother.
