In an interview Wednesday with Fox News Channel, Haley was asked if it's an open question about whether the USA team will compete at the Olympics in South Korea, given the tensions on the Korean Peninsula.
She also said that if invited to the White House after the Olympics she would decline.
Blackmun spoke on a conference call with reporters following the USOC's quarterly board meeting in NY.
Hwang said that during a phone conversation with South Korean President Moon Jae-in last week, President Donald Trump told the South Korean leader that American athletes and senior government officials would be heading to the Games. "We don't ever fear anything, we live our lives", Haley said. "We're gonna show up just like nearly 100 other nations and really looking forward to it".
During the White House press briefing Thursday, Sanders initially reiterated Haley's comments, saying there had been "no official decision" made on if American athletes would attend the Winter Games. The USOC is a nonprofit organization, not a government agency, though it does work closely with several federal branches. Heather Nauert, a State Department spokeswoman, tweeted, "We have a long-standing and successful relationship with the Republic of #Korea. What we will do is, we will make sure that we're taking every precaution possible to make sure that they're safe and to know everything that's going on around them".
The situation on the Korean Peninsula has further escalated in the wake of Pyongyang's nuclear test and repeated missile launches conducted in violation of the UN Security Council's resolution, with the most recent ballistic missile test being conducted in late November.
"I recall prior to the 2014 games in Sochi, there was a tremendous amount of apprehension about security issues related to those Games", said Larry Probst, USOC chairman.
