Yes, Ambassador Barton did go to the United States. It was planned, because he's very knowledgeable about the situation with respect to Madam Meng Wanzhou as well as the situation in which the two Michaels find themselves. He is in regular contact with Huawei, both in China and in Canada, and also in the United States, because of the presence of legal representatives of Huawei in the U.S. He is uniquely suited, along with Ambassador Kirsten Hillman, who is our ambassador to the United States, to work on this particular file.
I can't go into details, but I can tell you that both are very actively working on the file with respect to the two Michaels.
