Nancy Pelosi really doesn't want to see that wall built. She's got an army of very angry illegals following her around, and if she doesn't pander to them in just the right way, they start yelling. Nancy finds yelling upsetting, even if she can yell louder than anyone. So, to appease her base, she's decided to offer an alternative to building a wall.
That alternative is...mowing the grass along the border.
