NASA leader Raila Odinga has welcomed Co-principal Kalonzo Musyoka in the country after arriving on Wednesday morning.

In a press statement, Odinga stated that the coalition was encouraged by the return of Kalonzo and the tremendous recovery of Pauline Musyoka (Kalonzo's wife).

"I was deeply encouraged by the tremendous recovery Pauline has made and the fortitude with which they have gone through this trying moment. The NASA fraternity is encouraged by the return and commitment of our able deputy. Our prayers for full recovery continue to be with the family over this festive season," part of the statement read.

The former Vice president made his first public appearance on Thursday when he laid a wreath on the burial site of late Kitui West MP Francis Nyenze in Kyondoni village, Kitui County.

He went ahead and warned President Uhuru Kenyatta that they would be sworn in with Odinga if he failed to dialogue with them.

"Uhuru if you will not allow dialogue, Kalonzo and Raila will be sworn in. Don't blame us when we are sworn in," Kalonzo said.
