President Donald Trump's Senior Counselor Kellyanne Conway joined "Fox & Friends" Tuesday to discuss the resignation of Michael Flynn as national security adviser.

Flynn stepped down in the wake of revelations surrounding conversations he had with the Russian ambassador last year and several reports that he was not honest with Vice President Mike Pence about the situation, Fox News chief White House correspondent John Roberts reported.

Conway said the situation became increasingly untenable for Flynn, leading to his resignation.

"In the end, he (Flynn) felt that he had misled or misrepresented all the facts to the president and vice president," Conway said. "For that he was enormously and deeply sorry."

Conway said Flynn's 30-plus years of service as a military official and intelligence officer should not be overlooked in the wake of his resignation.

"In this particular case, there was an incident or so that just became unsustainable for him to carry on in that role, and that was the decision he made and the president accepted his resignation. ... It's not a particular contact or incident by itself. It's really the cumulative effect of that leading to incomplete or misleading forgetful information," Conway said.

In a statement, Flynn admitted he inadvertently briefed Pence with incomplete information regarding his correspondence with Kislyak. He added that the conversation with Kislyak was to "facilitate a smooth transition and begin to build necessary relationships."

According to reports, former acting Attorney General Sally Yates informed Trump that Flynn was vulnerable to Russian blackmail attempts.

After Flynn's resignation, Trump named Gen. J. Keith Kellogg as interim national security adviser. Conway said the president will take his time in considering who is the best fit to fill this role.
