Snow lay thick in the Pittsburgh suburbs as Takahiro Mori, a bespectacled, 67-year-old executive from Japan's Nippon Steel, huddled in a cluttered garage with community leaders to reassure them he was not giving up on a bid to buy the town's steel mill.

With Biden's incoming successor Donald Trump also voicing opposition to the planned purchase, the outlook was bleak.
