"So when the Parks Service prohibition of Confederate flags was added to the bill, then our understanding was that they heard from some of their extreme members within their caucus that they weren’t gong to help pass the bill unless they can have something out of it," McCollum said. "Our understanding is that is why this amendment was offered."
Not long after McCollum spoke TPM, House leadership canceled Thursday's vote on the entire bill, citing the debate over the Confederate flag language.
"That bill is gonna sit in abeyance until we come to some resolution on this," House Speaker John Boehner (R-OH) said of the Confederate flag amendments.
Rep. Ken Calvert (R-CA), who introduced the language that would have stripped the previous Confederate flag prohibition amendments, said in a statement Thursday that GOP leadership had asked him to bring the amendment on the request of some Southern Republican members.
"Looking back, I regret not conferring with my colleagues on the other side of the aisle, especially my Ranking Member Betty McCollum, prior to offering the Leadership's amendment and fully explaining its intent given the strong feelings Members of the House feel regarding this important and sensitive issue," Calvert said.
