Potential 2020 Democratic presidential candidate Sen. Elizabeth Warren is questioning this week's bombing of a network of ISIS tunnels in Afghanistan.

To reporters at a town hall meeting in Massachusetts, she said, "What is our overall purpose here?"

As the former Obama administration had before it, the Trump administration said the purpose of military actions in Afghanistan was to target ISIS leaders. Afghan officials said dozens of them were killed when the Pentagon dropped the so-called "Mother Of All Bombs" on Thursday. No civilians were killed, said the Afghans.

The plan to use the bomb for the first time was reportedly under consideration by the Obama team.

Despite the success, Warren said she needs to hear more about the situation. From the WBZ's video posted by America Rising Squared:

Warren: "You know, I want to hear more from the generals out in the field about why they thought this was the right bomb and this was the right moment. As is the case with every part of Trump's foreign policy, we're all trying to understand what is the strategy? What is our overall purpose here and so far, we're just not hearing it."

Reporter: "Do you think this was more of a message to North Korea?

Warren: "You know, if we can't figure out what it means, it's sort of hard to make that a message."
