Hi
OK, so I should use "said" and then either "were" or "had been". Actually I understand the usage of the past perfect (because it happened before) and I'm not sure why "were" is also correct?
And if we left "says," i.e., A press release issued today says that security issues .. (and now the second part should be in the past)
I'm quoting this example because in one of my books on business English the example starts precisely: A press release issued today SAYS .. (and then I'm supposed to write the second part of the sentence in the past tense)
