Ken Salazar, the new US ambassador to Mexico, has arrived in the Mexican capital. In his short arrival speech, Salazar promised to work alongside Mexican officials to address common challenges like the pandemic and immigration. “We will work to make sure we have an immigration system that works for both the United States and Mexico,” said Salazar after arriving at the Mexico City international airport. Salazar arrived in Mexico two days after Presidents Joe Biden and Lopez Obrador's top advisers met in Washington. Officials said they are eager to make progress on issues such as immigration, infrastructure and trade. The former Colorado Senator and Attorney will meet in the next few days with President Andrés Manuel López Obrador to present his credentials as ambassador.
