WASHINGTON, Feb 5 (Reuters) - U.S. President Joe Biden said on Friday he does not expect his proposal for a hike in the minimum wage to $15 an hour to be included in his $1.9 trillion COVID relief bill. “My guess is it will not be in it. But I do think that we should have a minimum wage, stand by itself, $15 an hour,” Biden said in an interview with the CBS Evening News. (Reporting by Eric Beech; Editing by Leslie Adler)
