grammatical usage of "had" and "that" in this sentence

Question

Occasionally had members that have been roundly censured in the national press.

I tried to make this sentence simple to understand. Like this,

"Had members that have been censured."

If I could remove 'had' and 'that', it would be "members have been censured." I can understand this sentence. But I'm pretty sure I cannot omit them. They look essential components in this sentence.

If so, I cannot even find what is a verb of this sentence.

"Had members that have been censured."

What is the "had" and "that"???

Remove the capitalization of "Occasionally" and merge the fragments, you get a long-yet-comprehensible sentence:

The greatly respected American Association of Zoological Parks and Aquariums (AAZPA) has had extremely dubious members, and in the UK the Federation of Zoological Gardens of Great Britain and Ireland has occasionally had members that have been roundly censured in the national press.
