Upset that the president was antagonizing trading partners in a way that could hamper supplies of critical equipment coming to the United States, foreign leaders and U.S. companies used a White House back channel, appealing to members of a task force reporting to Trump's son-in-law and senior adviser Jared Kushner. The backdoor approach was successful: Trump reversed course three days later and announced an "amicable" agreement: 3M could continue providing masks to foreign customers, while ramping up domestic production. Despite the president's caustic remarks about 3M, a senior White House official had praise for that company and another U.S. manufacturer of masks - Honeywell - for quickly agreeing to step up domestic mask production and distribution.
