Rep. Gluesenkamp Perez's official press release about this effort says the letter was sent to Mr. Bolko Graf von der Schulenburg and Mr. Constantin Freiherr von Wendt. It does not identify either addressee as "Prinz."

The investment firm's own website matches that: Salm Schulenburg says it is managed by Bolko Graf von der Schulenburg and Constantin Freiherr von Wendt. On the same page, it separately lists Constantin Prinz zu Salm-Salm as a different person. Salm-Salm & Partner's family page likewise says the company is owned by Constantin Prinz zu Salm-Salm and Constantin Freiherr von Wendt.

So the post's wording is inaccurate: the two people being urged in the letter are not "two German Princes." One is styled Graf and the other Freiherr; only Constantin Prinz zu Salm-Salm is identified with the title Prinz.

For English readers, standard dictionary references translate Graf as count and Freiherr as baron, which further confirms these are not both princely titles.
