The 47-year-old is well aware of the damage a Ryder Cup loss can do to a captain's reputation, having played under six-time major victor Sir Nick Faldo in Europe's defeat at Valhalla in 2008.
The Irishman was one of Bjorn's vice-captains at Le Golf National in September when Europe cruised to an emphatic 17.5-10.5 victory over the United States.
Harrington was a popular choice among Europe's victorious team to take on the captaincy and became a near-certainty when Lee Westwood announced he did not want to be considered for the role, preferring to target Italy in 2022.
Bjorn and past captains Darren Clarke and Paul McGinley are on the panel that selects the next captain along with European Tour chief executive Keith Pelley and a member of the Tour's Players Committee.
"It's not something I went into lightly", he said.
"It does make my job easier that I feel I have the confidence of the players", Harrington added.
"He's been a great ambassador for the country and golf and I'm sure he's going to do a great job for Europe as well".
Bergman returns to Washington, says money for border wall will reopen gov't
U.S. media reported that Mr Trump, when asked why he would not end the shutdown, had said: "I would look foolish if I did that". Mr Trump made the border wall a key part of his presidential campaign and said Mexico would pay for it.
"I really want to be a help. That's normally what we do and one of the reasons we've had success in the event is this elevation of vice captains into captains".
"It's not something I take on without a certain amount of trepidation", Harrington, a three-time major champion, said when he was presented as captain at a media conference at the European Tour's headquarters at Wentworth.
"The reminder we have every day is the Harrington Room where we have all his trophies from his amateur days right through to the Walker Cup, Ryder Cup, then the Majors and competitions around the world", Mr King said.
Paul McGinley described Europe winning in the U.S. as a "monumental" task but one that Padraig Harrington is the best man for.
I have to be part of that team and ensure that I find an edge to make the team perform to the best of their abilities and hopefully get a win.
"I felt it was the right time for me to go for it and when you talk to the other players I certainly have their support and when I talk to the vice captains and potential captains going forward it seemed to fit very nicely that I go and do the away match. You just have to know the man behind the scenes".
Pavard played in six of France's seven games at the World Cup finals, only missing their final group game against Denmark, and he scored his first global goal in the last-16 clash with Argentina.
"It is a natural graduation for Padraig, not just from his playing record, which is very stellar, but also through three vice captaincies".
