Hugh J. Schwartzburg '53 will testify in Washington today on the controversial Bricker Amendment to the Constitution, which would revise treaty-making power of Congress and handling of executive agreements. He will speak for the Collegiate Council for the United Nations, of which he is National Chairman.

Opposing the Amendment, Schwartzburg will face questioning from Senators Dirkson (R.-Ill) and Langer (R.-N.D.).
