Are there any records that show Obama was issued a green card?
Of course, Maricopa Co. Sheriff Arpaio can drive over to Maricopa Co. resident and DHS Secretary Janet Napolitano’s house and ask for them. DHS is the custodian of immigration records.
If necessary, Sheriff Arpaio can obtain a search warrant. And since Sheriff Arpaio is conducting a criminal investigation, he could call D.C. Police Chief Cathy Lanier and ask for cross-jurisdictional cooperation to conduct a search at DHS in DC.
Even better, since Sheriff Arapio has determined Obama’s BC posted on the WH website is a forgery, it’s not unreasonable to assume Obama is an immigrant to the U.S. Consequently, he can place Secretary Napolitano under arrest as a co-conspirator in elections fraud and indentity theft.
