Kyrsten Sinema goes independent days after Democrats secure Senate majority

Arizona senator changes party affiliation and says she will not caucus with Republicans

The US senator Kyrsten Sinema has switched her political affiliation to independent, leaving the Democratic party just days after it won a Senate race in Georgia to secure a 51st seat in the chamber.

I have joined the growing numbers of Arizonans who reject party politics by declaring my independence from the broken partisan system in Washington. I registered as an Arizona independent," she said in an op-ed for Arizona Central, a local media outlet.
