More than 35 newly-elected Congressmen will arrive in Cambridge Sunday to attend a six-day training conference sponsored by the Institute of Politics.

The program, which is co-sponsored by the House Committee on Congressional Relations, will "acquaint new members of the U.S. House of Representatives with analysis of the major public policy issues facing the Congress, and an explanation of how the legislative processes work in dealing with them," Jonathan Moore, director of the Institute, said Wednesday.

Gov. Michael S. Dukakis will co-lead a session on welfare reform.

"In light of present cost-control measures and Proposition 13 fever, there is probable reluctance on the part of Congressmen to undertake federal welfare reform programs. However, the governor is going to stress the validity of these programs and point out the inefficiencies of present programs, especially in the Northeastern states," W. David Stephenson, Dukakis press secretary, said yesterday.

Barbara S. Fischbein '80, chairman of the guests subcommittee of the institute's Student Advisory Committee, said that students have been invited to meet with the Congressmen from their areas for dinner and discussion this Tuesday evening.

"We hope to provide the students with an excellent opportunity to meet the new members of the next Congress," Fischbein said Wednesday.

Harvard professors planning to lead sessions at the conference include Otto Eckstein, Warburg Professor of Economics, and Edwin O. Reischauer, University Professor. Eckstein will discuss economic issues and budget priorities while Reischauer will give a session on "American Problems with Japan."
