Editor’s note: Roll Call photo editor Bill Clark gives his first-person report on how he got the above photo that made headlines Tuesday. 

I was standing in the Capitol with a few other photographers outside of the Senate Republicans’ policy lunch for the expected arrival of Treasury Secretary Steven Mnuchin. That’s when Jon Stewart — a stalwart advocate for 9/11 first responders — happened to walk by.

I followed him over to the Ohio Clock where he made a joke about the clock’s missing hands. Moments later, Majority Leader Mitch McConnell emerged from the Senate floor walking toward his office. I was hoping McConnell would stop to interact with Stewart, but he just walked by as Stewart stood there smiling.

A few minutes later, McConnell walked back to the Senate floor and Stewart thanked him for getting the 9/11 bill a vote in the Senate. 

The Senate later passed the bill by a vote of 97-2. The bill would extend a financial lifeline to thousands of victims suffering health problems from the Sept. 11 terrorist attacks. It’s now headed to President Donald Trump’s desk for signature.

Stewart testified earlier this year to ask Congress to address this measure, where he criticized McConnell and other leaders. On June 25, after pressure and publicity from Stewart, McConnell pledged action on the bill.
