Today there won't be much. All senators will give a speech. There are 19 senators on the committee so do the math.
Tomorrow will start the questioning. Things to watch for:
1. GOP senators will not go blood. They can't afford appearing too aggressive because the latino vote is huge.
2. Look for tough questions but just poking and prodding on the part of the GOP. They are going to look for weaknesses and try to exploit them but don't expect too much.
3. Expect non answers. Really long non answers.
