Speaker
On December 22, 1786, at the resignation of Thomas Mifflin as speaker of the Assembly, Wynkoop was elected speaker. He received forty-five votes and was escorted to the chair by Daniel Clymer. The oath was administered by a Mr. Evans. By December 26, 1786 around noon, Wynkoop resigned as speaker and Mifflin was re-elected.
Dissolving the Assembly
Before the Pennsylvania Constitution was adopted in 1790, the state had a unicameral legislature. Wynkoop was a member of that legislature. On Saturday, September 4, 1790, the Assembly made an address to the people of the state of Pennsylvania, indicating the body was resigning from power due to concerns that their authority had ceased at the adoption of the new state Constitution. The speaker of the Assembly, Richard Peters, declined to be seated. Wynkoop was instead seated in the speaker's chair for this address.
Miscellaneous notes
Wynkoop, along with Jacob Hiltheimer, escorted Richard Peters to the speaker's chair after his election. Peters was the final speaker of the unicameral general assembly. According to Wynkoop's obituary, he served nineteen years in the Assembly. It also notes that he served as speaker for several of those years. However, he was elected Bucks County Assessor in 1771 and 1773, which puts this claim in dispute. It could be correct if the writer meant to include both the State Assembly and the House of Representatives, assuming Wynkoop won his first election to the Assembly in 1775.
Wynkoop chaired a meeting on September 20, 1792 in Lancaster to select candidates for Congressional seats and Presidential electors. The list of electors does not include his name. However, an article dated August 27, 1792 does list his name as a Presidential elector.
