One day to go in the city mayor's race -- you can pass the time by looking through the super-cool interactive photo feature below from the PG photo staff. You're going to want to click through the A.J. Richardson gallery for sure:

Good morning. Great one for Bike To Work Day.

1. How can county payroll costs go up while the workforce is going down? Andrew McGill has the answers: part of it comes from the tradition of giving public employees less in salary but more in benefits.

2. Late round haymakers are being thrown in the city mayor's race. Today, Jack Wagner's called an early afternoon presser Downtown on jobs and development.

4. It's the 100th anniversary of the Kaufmann's Clock, which by contract requires us to link to the story about Jeep (grandfather of Eugene) DePasquale inviting councilwoman Michelle Madoff to kiss his *** under said timepiece.

5. Might as well go full Pittsburgh then -- there's a new documentary on competitive marbles, and Pittsburgh's domination of the kid sport.

Five Pennsylvania lawmakers will have a seat at the table during a pair of hearings aimed at finding out why the Internal Revenue Service singled out conservative groups for extra scrutiny.

U.S.  Reps. Mike Kelly, R-Buter; Allyson Schwartz, D-Philadelphia and Jim Gerlach, R-Chester, serve on the House Ways & Means Committee, which is scheduled to meet Friday with Acting IRS Commissioner Steve Miller and J. Russell George, treasury inspector general for tax administration.

Mr. Miller resigned over the scandal but is expected to stay on at least through next week. 

Sens. Bob Casey, D-Pa., and Pat Toomey, R-Pa., will get their chance to ask questions Tuesday at a similar hearing of the Senate Finance Committee onTuesday, Committee meets, but they’re already demanding answers.

Mr. Toomey, along with other Republicans on the committee, today asked Mr. George to investigate whether the IRS illegally disclosed conservative groups’ confidential applications for tax-exempt status, which appeared on the investigative journalism website ProPublica. The senators want to know who disclosed the documents, whether anyone was disciplined and more.

Mr. Casey, meanwhile, is asking for swift changes to IRS procedures.

“The American people should expect impartiality and fairness from their government. In this instance the IRS fell far short of that standard,” Mr. Casey said. “And the administration must move swiftly to ensure all responsible parties are held fully accountable.”

In announcing the House hearing, Ways & Means Chairman Dave Camp, R-Mich., said the public expects the IRS to be apolitical in enforcing tax laws.

“News that the agency admits it targeted American taxpayers based on politics is both astounding and appalling,” he said. “The Committee on Ways & Means will get to the bottom of this practice and ensure it never takes place again.”

Mr. Kelly said wants to know why it took the IRS so long to admit employees targeted conservative groups, and he wants to know why they did it.

"What was the purpose of it? What were they looking for? Was there a smoking gun?" he asked. "Nothing strikes fear in the heart of the American people like the IRS phoning you. I don't know of anything more intimidating." 

The committee’s ranking Democrat, Sander Levin of Michigan, said organizations requesting tax exempt status deserve unbiased treatment and should not be singled out because of their political views. 

As Andrew said below, Bill Heltzel at Public Source does a great job today of looking into "Pennsylvanians for Accountability," the shadowy social welfare group running ads against Gov. Tom Corbett's budget.

Like the Tea Party groups currently at issue in the IRS scandal, PFA seems engaged in political activity but doesn't have to disclose its donors and is seeking (like the conservative groups) tax-exempt status. It lists its addresses at the Union Project in Highland Park (though the director there has never heard of them) and at a UPS store in Fox Chapel. It is likely affiliated with America Votes, a progressive group.

One of the people who incorporated PFA told Heltzel (a former P-G reporter) that she doesn't know who started the group or why. Others ducked his questions.

From the story:

Dan Ford is named as the person at the America Votes address to whom documents should be returned. FCC records identify him as campaign director of the group. Ford, of Harrisburg, has worked as a union organizer for the American Federation of State, County and Municipal Employees, a trainer and recruiter for Service Employees International Union, and a political campaign manager.

When reached by telephone, Ford said he would talk later, but did not respond to several voice mail messages.

Linda J. Cook of Brookhaven, near Harrisburg, and Kevin C. Kantz of Edinboro are listed as incorporators. They are retired teachers who have been active in the Pennsylvania State Education Association. They did not respond to telephone messages requesting comment.
