There were early hints of compassion.
Then, as often happens, the Senator's personal experience coalesced into a policy proposal...

.. and finally today, the Senator had another--more conclusive--encounter.
UPDATE: This post has been updated to add Grassley's second tweet, which misspelled "deer" as "dear" and thus foiled our search. (h/t @benhjacobs)
