WASHINGTON (AP) — Vice President Kamala Harris plans to use a joint campaign appearance in the industrial city of Pittsburgh with President Joe Biden to say that U.S. Steel should remain domestically owned — coinciding with the White House’s earlier opposition to the company’s planned sale to Nippon Steel of Japan. The two are both attending Pittsburgh’s Labor Day parade on Monday. It will be the first time the two have shared a speaking slot on the political stage together since the surprising election shakeup. Harris coinciding with Biden is little surprise, but marks her taking a major policy position when her nascent campaign has offered relatively few of them.
