I’m delighted that The Post presented such a rich and well-deserved retrospective on Andrew Jacobs Jr.’s congressional career [“ ‘Parsimonious progressive’ served 3 decades in House,” obituaries, Dec. 31].

I served with Jacobs in Congress and can testify that he was highly regarded by his colleagues on both sides of the aisle for his idealism and his unwavering commitment to principle.

I suspect, though, that he would have been more than a little miffed by The Post’s description of him as a man “who served under seven presidents.” Jacobs’s career was defined in large part by his clear understanding that members of Congress don’t serve “under” any president; that the executive and legislative branches are separate and equal; and that this placed an obligation on him to stand firmly for what he, not the president or his party, thought was right. It was that understanding and commitment that made him such a fine example of what a congressman should be.
