PORTLAND, Ore. -- Danny Coulson, former Special Agent in Charge of the Portland FBI office told KXL News Tuesday evening that fired FBI Director James Comey had reached a point where he had to go.

"It was a 'lose lose' for him," said Coulson, who now runs a security firm in Texas.

It's better for him and the agency to move along, he said. Aside from a day of talking about the firing, agents "will go after this (Russia) case, hammer and tong."

FBI agents separate themselves from politics, he told KXL. Coulsen said while vigorously investigating the Iran-Contra affair, which scandalized the Reagan administration, he nevertheless voted for him.

He suggested that a replacement for Comey should be someone who is "ingrained in the FBI tradition." He suggested former FBI assistant director James Kallstrom. Coulson told KXL he would return to the bureau to work for Kallstrom.

"I'd Xerox papers for him."

In response to the firing of FBI Director James Comey, Oregon Sens. Ron Wyden and Jeff Merkley called for further investigation into possible connections between President Donald Trump's campaign and Russia.

“Comey should be immediately called to testify in an open hearing about the status of the Russia/Trump investigation at the time he was fired,” Wyden tweeted minutes after Comey's firing.

Merkley called for an independent special prosecutor.

"In case the need for an independent special prosecutor to investigate #TrumpRussia ties wasn't clear enough already...it sure is now," Merkley tweeted.

Former U.S. Attorney for Oregon Dwight Holton told KGW he has worked with Comey and says he's a man of tremendous integrity. The FBI, Holton said, should be free of politics.

"What the president has done here is dismiss the director of the FBI, who is currently investigating ties betwen his own campaign and a foreign power, Russia, then he will be empowered to replace the leader of this investigation with a person of his own choosing, despite his obvious connection to that investigation. It is very disturbing."

Trump, under the recommendation of Attorney General Jeff Sessions and Deputy Attorney General Rod Rosenstein, fired Comey on Tuesday, according to White House spokesman Sean Spicer.

“The FBI is one of our Nation’s most cherished and respected institutions and today will mark a new beginning for our crown jewel of law enforcement,” Trump said in a statement.

Comey has drawn criticism from the Democratic and Republican parties over the past year for the FBI’s investigation into Hillary Clinton's private email server, and the probe into Russia’s meddling in the U.S. election.

“I have been long been a critic of Director Comey, for his views about surveillance and torture, his stance on secret law and his conduct during the investigation into Secretary Clinton," Wyden said in a statement. "But Donald Trump’s decision to fire him now, in the midst of an investigation into Trump associates and their ties to Russia, is outrageous."

Last week, Comey inaccurately testified to the Senate Judiciary Committee about the Clinton email investigation.

The FBI is currently investigating any potential ties between Russia and the Trump campaign during the 2016 election.
