On Monday morning, President Trump misrepresented the voting process in Georgia and implausibly urged the Republican governor of the state to "outvote" his Republican foreign minister.
The tweet was the latest of Mr Trump's ongoing assault on the election results in Georgia and his top Republican official that sparked an intra-party feud in the state.
Georgia Governor Brian Kemp does not have the authority to do what Mr. Trump suggests. In addition, checking the signature is already part of the vote counting process.
When postal ballot papers are received, Georgian electoral officials check the signature on the envelopes. The ballot papers and envelopes are then separated to protect privacy. Checking the envelopes again during a recount would therefore be meaningless.
“Georgian law prohibits the governor from interfering in elections. The secretary of state, who is an elected constitutional official, has control over elections that cannot be overridden by executive order, "a spokesman for Mr. Kemp told the Atlanta Journal's Constitution.
The notion that "the governor has inherent executive power to suspend, investigate, or in any way interfere with this process is just not true," said Anthony Michael Kreis, professor of constitutional law at Georgia State University. "There is absolutely no plausible case here."
Unlike the federal government, Georgia does not have a single executive and its governor and state secretary have separate responsibilities. Even the governor's emergency powers are limited.
Mr. Kreis said the Georgian code is "very clear" about what a governor can do in a state of emergency. Mr. Kemp can move resources and funds and take temporary measures, said Mr. Kreis, but "he does not have the power to specifically disrupt elections."
Georgian Foreign Minister Brad Raffensperger continued to push back baseless allegations by Mr Trump and his allies of mass voter fraud in a press conference on Monday.
"The truth is important, especially when it comes to election administration," Raffensperger said. "There are people who exploit the emotions of many Trump supporters with fantastic claims, half-truths, misinformation and frankly, they seem to be misleading the president as well."
