Harris County TX GOP Chair Resigns After Racist Post

The Texas Tribune reports:

The head of the Republican Party in Texas’ largest county has resigned after less than four months on the job. Keith Nielsen, chairman of the GOP in Harris County, home to Houston, submitted a letter of resignation and the party’s secretary, Josh Flynn, said he received it Monday morning.

Nielsen was engulfed in controversy before he even became chairman. He won the job in March, but as he prepared to take office this summer, he faced widespread condemnation for posting a Facebook graphic juxtaposing a Martin Luther King Jr. quote with a banana.
