From this morning's Earlybird:

• Lobbying firms "were required to release first-quarter revenues on Tuesday, and some reported record earnings over the past three months as Congress considered major healthcare, energy and financial reforms," The Hill reports.

• "As Senate Democrats target the biggest banks with sweeping financial regulatory reforms, Wall Street is attempting a bank-shot attack, relying on third-party lobbyists not blamed for causing the economic crisis to make its case to Congress," Roll Call (subscription) reports.

• "Even as it waged major battles on health care and financial reform, the U.S. Chamber of Commerce on Tuesday reported a dramatic drop in lobbying expenditures for the first three months of this year compared with the last two quarters of 2009," Roll Call (subscription) reports.
