Promotes birther conspiracy about Obama Sr.'s INS application

Following a press conference by Arizona Sheriff Joe Arpaio claiming Obama's birth certificate was fraudulent, Trump tweeted: "Weird--why did BarackObama Sr. fail to list @BarackObama as his son in his 1961 INS application?" The tweet was part of his sustained effort to delegitimize President Obama's citizenship using debunked or misleading details from the "birther" movement.
