Integrating Google news feed

I am analyzing a requirement in which the client wants to integrate Google news feed into their CRM system, they want the accounts tab to show Google news relevant to the current account. Also they want to make sure users don't miss any news, which basically means storing news locally so that users can check back-dated news. Client has few thousand accounts so I need to write a daily job to get news for each account and store it in a database.

Can I do that? Of course I can't hit Google news servers 10,000 time every minute, I am okay with pulling news once a day over a period of few hours. But can I store the data returned by the google rss feed on my server in the first place? I don't get any clear idea from their support page https://support.google.com/news/answer/40796
