The Congressional Black Caucus, after meeting yesterday with U.N. Ambassador Andrew Young, accused Young's detractors of engaging in "scurrilous attacks" and "Red-baiting."

"As a result of this meeting, every member of the caucus is fully prepared to support Ambassador Young and to condemn all those who, in my opinion, represent rightwing thinking and who are mounting scurrilous and unnecessary attacks on the ambassador," said Rep. Parren J. Mitchell (D-Md.), the caucus chairman.

In its formal statement, the caucus said: "All decent Americans must speak out against the scurrilous attacks on members of the ambassador's staff on the floor of Congress. The attempt to Red-bait leading national figures is a shocking reminder that we have not fully escaped the mentality that plagued the country in the 1950s."

In its attack on "red-baiting," the caucus was referring to an atttempt last week by Rep. Robert E. Bauman (R-Md.) to strip $91,000 from appropriations for Young's Washington staff. In offering his amendment to take away the money, Bauman critized Young's appointment of Brady Tyson as a delegate to the United Nations Human Rights Commission.

"Mr. Tyson is apparently an avowed Marxist and a member of at least two front groups dominated by the Marxists and Communists. This was the same person that apologized to the Commission on Human Rights for what he said was the terible past policy of the U.S. Government regarding Chile," Bauman said in a statement inserted into the Congressional Record May 4.

Bauman's amendment was defeated 318 to 91.

The caucus yesterday praised Congress for its action. In its formal statement, the caucus also praised President Carter,saying that his support of Young "is well-jutified."

Young, who departed yesterday for a two-week tour of Africa, was not present when Mitchell made the statements of support to the press. He said earlier that he had attended the meeting at the request of the caucus to bried the members on U.S. policies toward Africa.

Young is a former Georgia congressman and former member of the Congressional Bank Caucus.

Asked if there was some concern among the current 16 caucus members that Young would be forced to resign because of his outspokenness, Mitchell said, "Those who are putting out those rumors and who have that kind of desire are very foolish and naive people."
