I don’t remember all the details, but President Trump offered NG to the DC devil-mayoress, and Pelosi was briefed by the FBI to have more security, and they both refused.
Regarding Trump calling the NG without governors’ request, the governors did not ask until finally I think in MN (?) and then Trump authorized. He went by the book. Governors have to ask. Unless it’s some kind serious (real) insurrection. If someone knows more or better, chime in!
That could be. But at rallies Trump will often talk about (as he did tonight) how he offered the WA and MN Governors to send in the NG and they declined, but he finally sent them in anyway. It could be a bit of a white lie from Trump, but who knows? Anyone who has watched a Trump rally knows not to take everything he says too literally. Could be the case here.
