A congresswoman who has been in politics for more than 20 years became visibly uncomfortable during a nationally televised interview about her alleged lack of manners on Nov. 24.

Rep. Maxine Waters (D-Calif.) appeared to squirm in her chair after MSNBC presenter Joy-Ann Reid discussed a “harsh letter” the congresswoman recently received that accused her of having no manners.

Housing and Urban Development Secretary Ben Carson (R) made the remarks after sending several letters to the congresswoman’s office, requesting bipartisan support to help more homeless people find shelter “as soon as humanly possible.” However, Carson became upset with Waters’ failure to respond or accept his many meeting requests.

“Basic manners elude you and it seems that instead of producing results, you’re more interested in producing cheap headlines at the President’s expense–like a true career politician,” the secretary said in the letter according to the Washington Times.

Waters did not appear to take the complaint seriously and dismissed it because she did not have time for him.

“He sent me a letter claiming that I had no manners, etc. I basically said to my staff, I really don’t have time to be bonded with somebody who does not know the difference between REO and OEO,” she told Reid according to Breitbart.

The congresswoman also accused Carson for being incompetent even though he had finished a doctor of medicine at the University of Michigan Medical School and worked as a neurosurgeon, chaired biotechnology company Vaccinogen, sat on the boards of Kellogg Co. and Costco Wholesale Corp., and been a regular contributor to both the Washington Times and Fox News.

“I mean, you know this guy just doesn’t have the background, the capability, the intelligence to do the job,” Waters said. “He does not know what he’s doing. He doesn’t care about this issue [of public housing].”

Waters made the remark even though Reid commented that Carson used to live in public housing and grew up in poverty.

She also expressed dissatisfaction with Carson always defending the president and undermining the U.S. presidency.

“He rises to the occasion to basically support this president any opportunity he gets,” she said. “They are hurting our country, they are undermining our democracy and being very destructive and I hope the American people can see that if we allow this president and his cabinet get away with what they are doing, they will be destroying the presidency and that office forever.”
