the concentration camp angle is a rather irrelevant appeal to emotion in criticizing Pelosi. She doesn't have the power to close them down or get rid of them. Even if she was right there with the Squad, she gets nothing accomplished about the existence of the camps, and all she would get out of such a position is not standing with the majority of the Democratic Party.
the Senate bill had bipartisan support. She even tried to fight it by getting an amended bill with guaranteed protections passed in the House which McConnell immediately rejected.
She has no power there, and as a leader, she doesn't have the ability to take a stance that the majority of her party disagrees with. Thems the bites of belonging to a party. And she would have never gotten to be Speaker if she was the type of person that disagreed with her party all the time.
The Democratic party as a whole dropped the ball on this issue. Primarily in the Senate where there wasn't even an attempt to twist McConnell's arm on it. There's little point in zeroing in on Pelosi over it.
