Democratic Sen. Kyrsten Sinema switches to independent

Democratic Sen. Kyrsten Sinema of Arizona says she has switched her registration to independent. But the first-term senator also says she doesn't plan to caucus with Republicans and that will ensure Democrats retain their narrow voting majority in the Senate. Sinema has frustrated Democratic colleagues at times with her overtures to Republicans and opposition to party priorities. She told the AP on Friday that that won't change much, but is “further affirmation" of a style "working across all the political boundaries” to get things done.
