“That’s what we were originally thinking of, and the congresswoman came up with the theory of the semi-postal stamp,” he said.

Fifteen original co-sponsors — nine Republicans and six Democrats — joined Stefanik in sponsoring the legislation, which does not yet have a Senate companion sponsor.

Seven of the original co-sponsors are from New York. Others are from Arizona, Guam, Minnesota, California, Illinois and Pennsylvania.

“I was proud to introduce it with such significant New York support and such bipartisan support,” she said.

The U.S. Postal Service will design the stamp, with input from House members on what invasive species might be featured in the design.

Stefanik said she does not yet have a preference.

“I will be working with my original co-sponsors to come up with some suggested invasive species,” she said.

Stefanik also introduced a separate resolution expressing it is “the sense of Congress” that invasive species control is important.

“It’s about awareness. That’s why I introduced two bills,” she said.
