1/ The 9/11 Commission wrote about the national-security threat of slow transitions/lack of cooperation during one. Since national security is one of the three legs of the GOP stool, you'd expect they get the risk & vulnerability Trump is exposing ALL Americans to right now:

2/ From the report:

"Since a catastrophic attack could occur with little or no notice, we should minimize as much as possible the disruption of national security policymaking during the change of administrations by accelerating the process for national security appointments. ...

3/ "We think the process could be improved significantly
so transitions can work more effectively and allow new officials to assume their new responsibilities as quickly as possible."

More...

4/ "The outgoing administration should provide the president-elect, as soon as possible after election day, with a classified, compartmented list that catalogues specific, operational threats to national security; major military or covert operations; ..."

5/ ...and pending decisions on the possible use of force. Such a document could provide both notice and a
checklist, inviting a president-elect to inquire and learn more." https://www.govinfo.gov/content/pkg/GPO-911REPORT/pdf/GPO-911REPORT-19.pdf

6/ Authors Tom Kean, a Republican, and Lee Hamilton, a Democrat, followed up on Sept. 11, 2020 -- this year -- writing in a post called, "The Impact of the 9/11 Commission on Current Presidential Transition Planning":

7/ "Presidential transitions are a time of great vulnerability for our nation, with a significant turnover in national security personnel occurring when the nation may be facing a foreign policy crisis or an adversary willing to cause significant trouble....

8/ "Many of the laws and norms that presidential transitions follow today were put in place based on lessons learned in the aftermath of the terrorist attacks of Sept. 11, 2001....

9/ "We found, among other things, that the Bush administration, like others before it, did not have its full national security team on the job until at least six months after it took office. ...

10/ "Since a catastrophic attack can occur with little or no notice as we experienced on 9/11, we concluded that the government must seek to minimize disruption of national security policymaking during the change of administrations."

11/ They recommend:"A requirement that the outgoing administration provide the incoming administration with a 'detailed classified, compartmented summary' of national security threats, major military and covert operations, and pending decisions on possible uses of military force"

12/ And:

"The ability of each major party candidate to submit requests for security clearances for prospective transition team members who may need access to classified information to carry out their responsibilities."

13/ They conclude: "To be truly effective and help protect our nation from national security threats during and soon after a presidential transition...

14/ "...our outgoing and incoming leaders must be cooperative, take these requirements and best practices seriously, and act in the best interests of the nation."

Is anyone translating this to President Trump? And when will Republicans in Congress suddenly remember it?
