A disgruntled former adviser to the Trump administration slammed the Republican Party for challenging the outcome of the presidential election.

Former U.S. National Security Adviser John Bolton has ridiculed President Donald Trump simply because he is exercising his right to scrutinize the way votes were counted at the presidential election.

“It is very important for leaders of the Republican Party to explain to our voters who are not as stupid as the Democrats think that in fact, Trump has lost the election and that his claims of election fraud are baseless,” he told ABC’s “This Week.” “This is all blue smoke and mirrors and think people will accept that if they see leaders, they respect, explain it to them.”

Bolton, who is already facing federal legal action over publishing national secrets in his new tell-all book, declared Democratic presidential nominee Joe Biden as the winner.

“Donald Trump lost what, by any evidence we have so far, was a free and valid election,” he said.

He denied election fraud took place despite a growing number of lawsuits arguing there was fraud and appeared to mislead viewers by claiming the courts have dismissed all litigation that is “pitching pennies.”

“The fact is that we have seen litigation in all of the key battleground states, and it has failed consistently,” he said.  “Where are their silver dollars? Where is the evidence? I think as every day goes by, it is clearer and clearer that there is not any evidence.”

The remarks came after the Commonwealth Court of Pennsylvania ruled Pennsylvania Secretary of State Kathy Boockvar (D) acted above the law when she doubled the grace period for accepting postal votes to six days after the original 8 p.m. deadline on Nov. 3.

“Kathy Boockvar, in her official capacity of secretary of the Commonwealth, lacked statutory authority to issue the Nov. 1, 2020, guidance to respondents County Boards of Elections insofar as the guidance purported to change the deadline … for certain electors to verify proof of identification,” President Judge Mary Leavitt said in the court order. “[This was] based on Secretary Boockvar’s interpretation and application of the Pennsylvania Supreme Court’s decision in Pennsylvania Democratic Party versus Boockvar.”

Leavitt also ruled that postal votes must be excluded from the final count if proof of identification was provided between Nov. 10 and 12 and after the Nov. 9, six-day grace period.

President Trump described Bolton as one of the “dumbest people” who he has ever worked with.

“A sullen, dull and quiet guy, he added nothing to national security except, ‘Gee, let’s go to war,'” he said on Twitter. “Also, [Bolton] illegally released much classified information. A real dope!”

The Trump 2020 campaign is also not the only plaintiff to launch legal challenges about the election outcome.

“Many of the court cases being filed all over the country are not ours but rather those of people that have seen horrible abuses,” the president said on Twitter. “Our big cases showing the unconstitutionality of the 2020 election, and the outrage of things that were done to change the outcome, will soon be filed!”
