I thought the question was more about the legality of lifting the content from another news source?
I don’t know the answer from a legal standpoint, but ethically it would raise these flags for me:
Is the content you are lifting behind a paywall? If so, integrating it to your free site is pretty poor behaviour.
Is the content you are lifting on a site that features advertising? If so, integrating it into your site limits their ability to maintain their revenue - which is also poor behaviour.
Are you lifting content in such a way as it appears you wrote the content, or will you provide ample attribution and back links? The former is poor behaviour, the latter depends on the above questions.
Anyway - I am not a lawyer, I am not your lawyer, this is not legal advice etc…
