Clinton wins Puerto Rico's democratic primary

Hillary Clinton has claimed victory in the Puerto Rico Democratic presidential primary, putting her closer to securing the number of delegates needed to win her party's White House nomination. 
Two days before Tuesday's primaries in California and five other states, Senator Bernie Sanders repeated his pledge not to concede even if Clinton acquires enough delegates to reach 2,383, the threshold for securing the nomination. 
A win in California is critical to Sanders's plan to stay in the race through the convention and would give him a significant lift. 
But with her victory in the Puerto Rico primary on Sunday, Clinton is only 28 delegates short of the threshold and will most likely declare victory on Tuesday.
