Eric Greitens, a sometimes brash outsider whose unconventional resume as a Rhodes Scholar and Navy SEAL officer made him a rising star in Republican politics, abruptly announced his resignation Tuesday after a scandal involving an affair with his former hairdresser led to a broader investigation by prosecutors and state legislators.

The trial of Missouri Gov. Eric Greitens was halted Monday, the third day of jury selection, but officials said they will refile the felony invasion of privacy case using a special prosecutor.
