During this time he was a member of the Republican National Committee from 1892 to 1896. In 1897, Simon was again President of the Senate; the 19th Oregon Legislative Assembly, however, did not organize for its 1897 regular session (due to a dispute over leadership in the House), and no legislation was passed. Due to this inability, a special legislative session was held in 1898 where Simon served as President, and where he served for the final time in the Oregon Senate.
