This was one of the "honorary professorships and doctorate degrees" that were issued by Professor Clyde Rivers, the International Commissioner of the Latin University of Theology, based in Inglewood, California.

[5]On 19 December 2008, Kalonzo Musyoka was honoured with a Doctorate in Humane Letters (honoris causa) in recognition of his achievements in peace making, conflict resolution efforts, sustainable community development and humanistic ideals by Kenyatta University during its 25th graduation.

Musyoka stayed in KANU, renewed his parliamentary position and was appointed as the Minister for Foreign Affairs and International Cooperation.

He termed the illicit mineral trade which fuels and finances what he called 'the cause of incessant conflicts, environmental degradation but ultimately and sadly too, poverty'.

Kalonzo Musyoka was involved in the Sudan peace process between 1993 and 1997 and he was part of the team that reconstituted the draft establishing IGAD in 1995.

In late August 2004, he was additionally removed from his position as chairman of the Sudanese and Somali peace talks and was replaced by John Koech.

Many observers questioned whether the presidential hopefuls of ODM-Kenya, particularly Raila and Musyoka, could unite to support one common candidate for the general election.

December 2007 polls put Odinga ahead and Kibaki following closely, Kalonzo however said that "atapitia katikati" (passing between two people).

[19] Amid a violent crisis over the results, with supporters of Odinga disputing the outcome, Kibaki appointed Musyoka as vice-president and Minister of Home Affairs on 8 January 2008.

[20] Musyoka expressed gratitude to Kibaki and, referring to the ongoing dispute and violence, said that he was "intensely aware that the appointment has come at a difficult time when our nation is going through a painful moment".

[25][26] When the first round of the presidential election took place on 4 March 2013, Uhuru Kenyatta was declared the president-elect of Kenya by the Independent Electoral and Boundaries Commission.

[28] In the 2022 elections, Musyoka announced that he would vie for presidency; he however dropped his presidential bid and supported Azimio la Umoja candidate Raila Odinga.

[30] In July 2019, Dr Kalonzo Musyoka was appointed by President Uhuru Kenyatta as a special envoy to the republic of South Sudan.

[31] In February 2020, he was able to broker a peace deal in South Sudan between President Salva Kiir and former rebel leader Riek Machar.
