Chambers estimated the meeting consisted of 40–50 men and women of different nationalities who spoke predominantly English, Greek and Yiddish.
Chambers claimed that Krieger and his wife Carol were largely in charge of the party's decision to admit him.
According to Chambers, Krieger (whose party membership was unknown to the paper) "pushed sales by giving bicycles to enterprising newsboys who, on competitive principles that would later be known as Stakhanovite, sold the most copies of that capitalist newspaper."
He also got Chambers to study Marxism, most notably at the Rand School in a class on "the law of social revolution" taught by Scott Nearing.
[1] In 1978, over a footnote,[6] Krieger sued for libel against Allen Weinstein, author of Perjury; Alfred A. Knopf, Inc., the book's publisher; and The New Republic magazine.
For example, the New York Magazine gave its article on the lawsuit the title "Communist Sues Hiss Historian.
"[6] Newspapers reported that The Nation told the Associated Press how to locate Sam Krieger, Chambers' sponsor for Communist Party membership in 1925.
"[14] Finally, Victor Navasky himself stated "Krieger [was] an important figure in the Hiss case because he introduced Whittaker Chambers into the Communist Party.
I was arrested in Bridgeport, Conn., for breaking up a German Bund meeting and leading a march of unemployed snow shovelers on city hall against a right-wing Socialist mayor."
[16] An unnamed source placed Krieger's papers in the Archives of Labor and Urban Affairs at Wayne State University in March 1995, opened for research in August 1996.
