Odinga says last year's elections, won by President Uhuru Kenyatta, were rigged.
A Kenyan opposition lawyer, Miguna Miguna, has been charged with treason over the mock "swearing in" as president of opposition leader Raila Odinga.
At least one other opposition figure has been arrested. So far police have not arrested Odinga. He was granted bail of 50,000 Kenyan shillings ($500) but has remained in police custody with his whereabouts unknown until he appeared in court in Kajiado County, neighbouring Nairobi, on Tuesday to hear the charges.
Miguna's lawyers have now applied to have the case transfered to Milimani-with the judge due to rule Tuesday afternoon on the matter.
Justice Luka Kimaru has directed the DPP to appear before court at 12:00pm to confirm whether Miguna has been charged.
"We are back on air", said Joe Ageyo, the managing editor of Kenya Television Network.

Mr. Edwin Sifuna, his lawyer rushed to court to obtain orders directing that his client be released on Sh50,000 bond pending his arraignment in court on Monday.
Odinga's supporters protested against the charges, blocking roads and clashing with police in the western city of Kisumu, a Reuters witness said. "The government was and is aware of the role of some elements in the media fraternity who participated in furtherance of this illegal act", Interior Minister Fred Matiang'i said at the time.
Also on Tuesday, the government suspended the passport of David Ndii, an opposition strategist, according to a letter he posted on Twitter.
Two Kenyan television stations have resumed broadcasting after being taken off air for plans to show a rally held by the country's opposition leader.
They bashed Duale and the the Jubilee administration he represents for blatantly breaking the law by continuing to detain Miguna Miguna even after a court ordered for his release on Friday.
The Supreme Court later nullified the August election on procedural grounds and Kenyatta won a repeat poll in October after Odinga boycotted it, claiming it would not be fair.
