No, a grand jury has the power to subpoena witnesses and review the evidence. Whether they choose to do so is up to them.
But, as Sol Wachtler (in)famously claimed: "district attorneys now have so much influence on grand juries that "by and large" they could get them to "indict a ham sandwich."
It will be interesting to see if this grand jury takes their job seriously, or just rubber-stamps the indictments.

Your post makes no sense in regards to my post. We were discussing discovery by the defendant. Evidence provided to the GJ are not provided to the defendant until after he is indicted.
