I think that's supposed to be Schumer. But I don't think anyone from the Democrats wants to impeach Pelosi.
There's going to be pressure mounting on her either to allow an impeachment inquiry to begin or to step down as Speaker.
And frankly, they should impeach--just not on obstruction. (The argument "you can't have obstruction without an underlying crime," while wrong, will resonate with all too many people.) They should impeach over emoluments, because on that one they have Trump completely cold (remember, Jimmy Carter had to sell his peanut farm), and it's actually a Constitutional demand on the President, and so any Republican who votes against impeachment or conviction can be instantly branded as not giving a fuck about the Constitution.
I still suspect you'll see Pelosi move on obstruction after the debt ceiling and government funding bills are finally done later this year. Until then, they can't risk giving Trump a reason to be a moron, as he can single-handedly block those bills, and he won't understand why passing those bills is so important. After all, declaring bankruptcy and laughing has been his go-to business move for most of his life; why wouldn't it work for the US too?
Trump doesn't need a reason to be a moron on that stuff. He already set a record for the longest government shutdown; who says he won't try again? (Trump can rally his base against any Republican who votes to override his vetoes, after all, and they saw what happened to Mark Sanford, they're seeing what's happening to Justin Amash, and they have the lion's share of Senators up for reelection this time around.)
And bankruptcy is, as you say, his business model, so he doesn't really need a reason to veto the debt ceiling bill, either.
So there's still going to be pressure on Pelosi either to allow an impeachment inquiry or to step down--or, perhaps, if Trump
does veto one of those bills, to try to get enough Senate Republicans (who aren't up for reelection) onside to invoke the 25th Amendment.
