It is rare to see anything bipartisan in Congress nowadays. This is why it bears notice that a bipartisan group of 11 members on the House Ways and Means Committee has released a “Dear Colleague” letter, challenging new legislation that could harm charitable giving.

The House version of the so-called Accelerating Charitable Efforts Act is a companion to the failed S.B. 1981, introduced last year by Sens. Angus King, a Maine independent, and Chuck Grassley, an Iowa Republican. Both measures would handcuff givers who have donor-advised funds, threaten donor privacy, and discriminate against family foundations.
