King - who boasts a history of racist rhetoric and support for white nationalists - questioned in an interview with the New York Times last week why terms like "white supremacist" are considered offensive.
"I have a scheduled meeting with him on Monday", he said, vowing: "I tell you this, action will be taken".
"Congressman Steve King's recent comments, actions, and retweets are completely inappropriate", tweeted Ohio Rep. Steve Stivers, then the chairman of the National Republican Campaign Committee. "Anything less than these substantive actions is another tacit acceptance of racism from the Republican Party", Bass said.
"We're not asking the Democrats to do something they haven't done before".
In his interview with the Times, King said he's OK with immigrants of various races legally entering the us ― so long as American culture stays white and European.
"I will not stand back as a leader of this party, believing in this nation that all are created equal, that that stands or continues to stand and has any role with us".
Yet still, the party struggles with a negative perception on civility and fairness brought on by people who make comments like King, or the people in the Republican Party who remain silent instead of ridiculing comments like King's. We all ought to stand up against it, but it's easy when the Democrats condemn a Republican. King asked. "Why did I sit in classes teaching me about the merits of our history and our civilization?" He also told CNN, "I'd like to see an America that's just so homogeneous that we look a lot the same". Those that he serves on include the agriculture and judiciary committees.
"We have made significant progress in our nation, and while there is still work to do, we can not let these intolerant and hateful views hold us back".
It's not the first time some Republicans have denounced King, nor is it the first time King has said his intent is to defend "Western civilization". "We can not continue down this path if we want to continue to be a great nation", she wrote Saturday morning.
Bass, in her statement, compared King with President Donald Trump. "Further, I condemn anyone that supports this evil and bigoted ideology which saw in its ultimate expression the systematic murder of 6 million innocent Jewish lives", he said.
In November's election, King narrowly defeated his Democratic challenger, Democrat J.D. Scholten, by 3 percentage points.
