“I am determined to pass this bill with or without consensus,” Netanyahu told a meeting of his Likud Party faction last month. “It is very important for securing the future of the nation of Israel, in the Land of Israel, in the State of Israel.” (Canada stays mum on controversial Israeli bill – CBC news Dec.14 2014)
Does “a meeting” here mean “a group of people”?
The word meeting can be used in the meaning of either an occasion (that people meet) or the people in a meeting. In Netanyahu told a meeting of his Likud Party faction last month, it makes more sense to understand it as “a group of people”, as you suggested.
From Macmillan Dictionary:
1. an occasion when people gather to discuss things and make decisions, either in person or using phones, the Internet, etc.
a. [formal] the people involved in a meeting
I reported to the meeting on my progress.
b. an occasion when two people meet either unexpectedly or as planned
I liked him from our first meeting.
