During the superheated political environment which surrounded the Korean War, Pressman seems to have stepped back from his previous communist affinities.
In 1950, Pressman resigned from the American Labor Party because of "Communist control of that organization," which was reported in the press and which signaled HUAC that Pressman was at last ready to talk.


Called again before Congress to give testimony on Communist Party activities, on August 28, 1950, Pressman reversed his previous decision to exercise his Fifth Amendment rights and gave testimony against his former comrades.
 Pressman stated:  
In my desire to see the destruction of Hitlerism and an improvement in economic conditions here at home, I joined a Communist group in Washington, D. C, about 1934.
My participation in such group extended for about a year, to the best of my recollection.
I recall that about the latter part of 1935— the precise date I cannot recall, but it is a matter of public record — I left the Government service and left Washington to reenter the private practice of law in New York City.
And at that time I discontinued any further participation in the group from that date until the present.

   He stated that he had no information about the political views of his former law school classmate Alger Hiss and specifically denied that Hiss was a participant in this Washington group.
 He indicated that in at least one meeting of his group, perhaps two, he had met Soviet intelligence agent J. Peters.
Although he made no mention of having himself conducted intelligence-gathering activities, his 1950 testimony provided the first corroboration of Chambers' allegation that a Washington, DC communist group around Ware existed, with federal officials Nathan Witt, John Abt and Charles Kramer named as members of this party cell.

TIME magazine mocked Pressman in its reportage in the issue following his hearing:  
Like many another smart young man who followed the Communist line, sharp-eyed, sharply dressed Attorney Lee Pressman did very well for a long time.
Har-vardman Pressman launched his leftward-turning career in Henry Wallace's AAA back in 1933, ended up as chief counsel of the CIO.
He held the post for twelve years.
But though he was a skilled labor lawyer, his fellow-traveling finally became too much for Phil Murray; 2½ years ago, Murray tearfully threw him out.

 His star did not entirely wane.
He became a power among the back-room Reds who steered Henry Wallace through the presidential campaign.
But when the Korean war began, he, like Wallace, began slipping away from his Commie cronies.
California's Congressman Richard Nixon, scenting opportunity, decided to call him before the House Un-American Activities Committee and ask him a few questions. (
Once before, when Whittaker Chambers named Pressman as a member of the same elite apparatus as Alger Hiss, Pressman had taken refuge in the Fifth Amendment, refused to answer Congressmen's questions.)

 Last week, Pressman decided to reverse his field... 
 This week ... he reluctantly consented to name three men who had been fellow Communists in the '30s—John Abt, Nathan Witt and Charles Kramer...
