Surprised by this: Why would Congress need to investigate the funds distributed by a Catholic Charity?
Seems like the US bishops (yeah right) would be responsible for that audit - and stop the charges before they began! Then again, is the pope Catholic?
Two reasons:
1) CRS is tax-exempt, receives federal funding and is flaunting the Mexico City Policy.
2) As you noted, despite pleas from lay Catholics, the USCCB has failed to curb CRS's illegal funding of abortions.
As a side note: Trump's judicial system has been more sympathetic to opening churches than most of the lazy, cowardly US bishops.
