 Coffee switched places with Morgan for one month, July 2007, to symbolize the unity between the two parties.While Coffee held the office of president "pro tempore" in July, Morgan served as the co-president "pro tempore".Morgan and Coffee took turns presiding over the Oklahoma Senate and, under the agreement, Morgan only had appointment authority as long as Coffee assented to the appointment, effectively making them both fully vested with the duties and rights of president "pro tempore".
