The number of seats in the House would rise from 435 to 437, because the deal that smoothed the bill through also gives an extra seat to Utah, in the expectation that the western state would elect a Republican to balance the Democrat DC was likely to elect.

ECONOMIST: Voting rights for DC

The style for DC is represented by the constant balance that must be maintained between its local and federal identities, between radicalism and conservatism, between the new and the old.
