(CNN) – Efforts to keep President Barack Obama's name off of the Kansas presidential ballot were halted Monday when a state board ended its probe over questions about the president's place of birth, the Kansas Secretary of State's office confirmed.
The all-Republican board made its decision after the person leading the objection, Manhattan, Kansas resident Joe Montgomery, dropped his challenge on Friday saying he had received threatening phone calls.

Last year, Obama released his long-form birth certificate from Hawaii to quell speculation that he was not a U.S. citizen and may be constitutionally ineligible to serve as president. He has previously released a certification of live birth during the 2008 campaign. Both documents show that he was born in a Hawaii hospital on August 4, 1961. Contemporaneously published newspaper announcements also noted the birth in the Aloha State.
