THE CAUCUS; Senate Weighs Fate Of Impeached Judge.

The proceedings in the Senate on Tuesday were as remarkable as the charges that lawmakers there were asked to weigh. As tax policy debates swirled around the Capitol, the Senate on Tuesday began pondering the fate of Judge G. Thomas Porteous Jr. of Federal District Court in Louisiana, whom the House of Representatives impeached in March on four articles of ''high crimes and misdemeanors'' stemming from charges that he received cash and favors from those with business in his court. This is only the 12th impeachment trial of a judge in Senate history. [ABSTRACT FROM AUTHOR]
