WASHINGTON (AP) — When conspiracists suggested Friday that the Obama administration had engineered a sharp drop in unemployment to aid President Barack Obama's re-election, the response was swift.
Career government officials, economists and even some Mitt Romney supporters issued a collective sigh.
The staffers who compute the U.S. unemployment rate work in an agency of the Labor Department. Officials who have overseen the work say it's prepared under tight security with no White House input or supervision.
"To think that these numbers could be manipulated. ... It's impossible to do it and get away with it," said Keith Hall, a former commissioner of the Bureau of Labor Statistics, the agency that calculates the unemployment rate.
"These numbers are very trustworthy," said Hall, who was appointed by President George W. Bush and whose four-year term ended in January.
The figures that produce the unemployment rate are crunched by several dozen people at the bureau. The only BLS employee appointed by the White House is the commissioner, who operates independently of the White House.
The job is now vacant but is being handled by Acting Commissioner John Galvin, who has worked at the BLS for 34 years.
Yet conspiracy theorists came out in force Friday after the government reported a sudden drop in unemployment a month before Election Day — to 7.8 percent for September from 8.1 percent in August.
Their message: The Obama administration would do anything to ensure a November victory, including manipulating unemployment data. Labor Department officials, joined by Democrats and some Republicans, called the charges implausible.
That didn't stop the chatter. The allegations were a measure of how politicized the monthly unemployment report has become near the end of a campaign that's focused on the economy and jobs.
The conspiracy erupted after former General Electric CEO Jack Welch, a Republican, tweeted his skepticism five minutes after the BLS announced the unemployment rate at 8:30 a.m. Eastern time.
"Unbelievable jobs numbers..these Chicago guys will do anything..can't debate so change numbers," Welch tweeted, referring to the site of the Obama campaign headquarters.
The drop in unemployment was announced two days after Obama's lackluster performance in his first debate with Romney.
Republican Rep. Allen West of Florida soon announced via Facebook that he agreed with Welch.
"Somehow by manipulation of data we are all of a sudden below 8 percent unemployment, a month from the presidential election," West wrote. "This is Orwellian to say the least."
The Obama administration was forced to defend Labor's statisticians and economists against accusations that came without supporting evidence.
"No serious person ... would make claims like that," said Alan Krueger, chairman of the White House Council of Economic Advisers.
The monthly jobs report is prepared with raw data collected by Census workers. The workers interview Americans in about 60,000 households or visit them door-to-door.
People are asked whether they're employed and, if so, whether their jobs are full or part time. The Census workers gather other information about the respondents' education, age and gender and ask whether they're self-employed.
