AP Source: Clinton expected to receive AFL-CIO endorsement

WASHINGTON (AP) — Presumptive Democratic presidential nominee Hillary Clinton is expected to be endorsed next week by the AFL-CIO, the nation's largest labor federation, in another sign of Democrats shifting toward the general election against Republican Donald Trump.

The powerful labor federation represents 12.5 million workers and is a key member of the Democratic party's coalition.

[...] some labor activists, including many rank-and-file members who support Sanders, have questioned Clinton's past support for trade deals, including her role as secretary of state in the early development of the Trans-Pacific Partnership.
