The contempt of Congress trial of Leon J. Kamin '48 will resume this morning to iron out several items of unfinished business.

Judge Bailey Aldrich '28 will spend part of the day listening to the tape recordings he admitted as evidence Thursday. The tapes were made during the January 1954 hearing, at which Kamin testified before Senator Joseph R. McCarthy.

Kamin's lawyers will probably present a new motion for a judgment of acquittal, using evidence they presented Thursday and Friday.

Aidrich may announce when he will pass on the defense motion, or when he will give his verdict on the two remaining counts of the indictment against Kamin.

They had presented a nine-point motion for acquittal immediately after the prosecution rested its case last Monday. Aldrich responded to it only to acquit Kamin on two counts, ruling that the questions on which the counts were based were not pertinent to the subject into which McCarthy was inquiring at the hearing.

The defense evidence presented last week concentrated on whether Kamin was informed of the subject-matter of the hearings. It has, however, requested Aldrich to take note of a long list of documents relating to the Senate Government Operations Committee and its Investigating Subcommittee.

The defense will ask Aldrich to admit testimony to the trial record which it took out of turn from McCarthy and his former chief counsel Roy M. Cohn three weeks ago.
