Congress returns on September 5 from its recess for the Republican National Convention and the August district work period. Expect rapid changes in schedule during the next several weeks as the election approaches. The following hearings, markups, and conference committees have been tentatively scheduled for the coming weeks by the Senate and House of Representatives. All dates and times have yet to be announced; the committee, subcommittee, or conference committee holding the hearing, markup, or conference will be setting schedules in the next few days. All offices on Capitol Hill may be reached by telephoning 202-224-3121.
