Reed followed many of the prominent Bolshevik leaders closely during his time in Russia.

Her news stories, distributed by Hearst during and after her trips to Petrograd and Moscow, appeared in newspapers across the United States and Canada in the years immediately following World War I.  A collection of articles from her first trip was published in book form as "Six Red Months in Russia" in 1918.  During the next year, she defended the revolution in testimony before the Overman Committee, a Senate subcommittee established to investigate Bolshevik influence in the United States.  Later in 1919, she undertook a nationwide speaking tour to encourage public support of the Bolsheviks and to denounce armed U.S. intervention in Russia.

Max Wexler (also spelled Vexler or Wechsler, November 4, 1870 – May 14, 1917) was a Romanian socialist activist and journalist, regarded as one of the main Marxist theorist of the early Romanian workers' movement.  Active in the first Romanian socialist party, the Romanian Social Democratic Workers' Party, he became dissatisfied with the party's passivity and its failure to openly support political rights for the Romanian Jews, initiating a separate Jewish socialist group.  Following the party's demise, he was one of the main activists for the revival of the socialist movement in Iaşi, introducing to Marxism many future leaders of the Romanian socialist parties.  Sympathetic to the 1917 February Revolution, he was arrested after attempting to gain the support of Russian soldiers present in the country during World War I. Wexler was assassinated in custody shortly after, with the Romanian authorities suppressing any formal enquiry into his death.
