National Security Advisor Mike Flynn has resigned, after his calls became public knowledge thanks to the FBI. The Democrat "Resistance" can claim this scalp. It's a minor win for them, effectively a successful rear-guard action in an overall retreat, to use a military metaphor.
Looks like Trump will have to get tougher about nailing civil service leakers and he must get rid of all the holdover political appointees ASAP, even if it leaves temporary holes. There are other qualified people and, if appointed now, whatever they were up to pre-inauguration will be of less moment as they were not Trump insiders at the time.
