Pennsylvania Republican senatorial candidate Dr. Mehmet Oz this week disavowed a series of columns bearing his byline arguing for gun control in a statement to Fox News Digital.

Oz’s byline previously appeared in a series of articles in his “YouDocs” syndicated column co-authored with business partner Dr. Michael Roizen.

At various points in the column’s run, notably from 2017 to 2019, the articles praised or advocated a variety of gun control legislation initiatives, including assault weapons bans, red flag laws, New Zealand-style gun buyback programs, universal gun purchaser licensing and mandatory waiting periods.
