Congress has a lot of touchy issues to deal with these days, including one that boils quite literally beneath their feet.
A painting, entitled "Untitled #1," by former Missouri high school student David Pulphus, has been on display in the busy underground walkway between the Cannon House Office Building and the Capitol since June 2016.
But as the new year arrived, the painting touched off a cultural tug-of-war after some Republican lawmakers noticed what was in it.
In a montage of images, the painting shows a street protest in Ferguson, Mo., confronting police. Some of the people have the heads of animals, including the heads of razorback pigs on the police.
The unflattering depiction of police was too much for some members of Congress to take. Three times, Republican lawmakers (Rep. Duncan Hunter of California, Doug Lamborn of Colorado and, as a team, Dana Rohrabacher of California and Brian Babin of Texas) have taken the painting down and delivered it to the office of Rep. William Lacy Clay, a Missouri Democrat whose district includes Ferguson.
