"This is a firing that is an attempt to obstruct the investigation into ties between Russia and the Trump campaign, and I'll tell you why I strongly believe that," Kaine said on ABC's "Good Morning America." "There's a pattern. Deputy Attorney General Sally Yates went to the White House and said Gen. Flynn was compromised by and lying about Russia and then she was fired."

Kaine added that when former national security adviser Michael Flynn's ties with Russia were "finally made available to the public," he was also fired.

"Jeff Sessions was caught misleading the Senate Judiciary Committee about his ties with Russia. He had to recuse himself," Kaine said. "And now the FBI director in the middle of an investigation into the Trump ties with Russia gets fired in a most unusual matter."

Kaine called for a special prosecutor.

"There's a pattern here," he said. "There's more to come."

In a separate interview on MSNBC's "Morning Joe," Kaine said Trump is "deeply insecure" and "very, very concerned about this investigation."

Trump on Tuesday fired Comey, who had been leading the investigation into potential ties between the Trump campaign and Russia.

The dismissal came in a signed letter from Trump to Comey that said it was time for a "new beginning" at the nation's "crown jewel of law enforcement."

It shocked Washington and sparked outrage from Democrats, who said the president was trying to shut down the FBI's investigation.
