Actually, both statements are true, aren't they?
The church's official doctrine states life begins at conceptions, I think everyoe knows that.
But the individual church members, which also are "the church", are conflicted, especially in the US.
Is the church the people, the doctrine, the Pope or the building? And how do we know to which Pelosi was referring?
Certainly one definition of "church" is the "body of its membership."
She specifically talked about church officials being conflicted. Look for the interview. Its easy enough to find.

If you care to look the vast majority of this country consider themselves Christians. Our country was founded on Christian principles. Their are lunatics on BOTH sides of the aisle but I think you are being a little narrow minded. Clearly you need to meditate a little longer. One prayer at a rally is hardly comparable to 20 years with a pastor with many sermons. EVERYONE knows he's LYING when he says he didn't hear them. PLEASE. if you believe this I've got some prime swamp land to sell you.
