Catch up on the top industries and stocks that were impacted, or were predicted to be impacted, by the comments, actions and policies of President Trump and his administration with this weekly recap compiled by The Fly:

1. CHINA TARIFF FIGHT ESCALATES: On Wednesday, U.S. Trade Representative Robert Lighthizer confirmed that this week the President directed him to consider increasing the proposed level of the additional duty from 10% to 25% on a proposed list of Chinese goods previously announced on July 10. "The increase in the possible rate of the additional duty is intended to provide the Administration with additional options to encourage China to change its harmful policies and behavior and adopt policies that will lead to fairer markets and prosperity for all of our citizens," Lighthizer said. In response, China's Ministry of Commerce described its plans for four different types of tariffs on $60B of U.S. goods.

2. FUEL ECONOMY LEVELS ROLL BACK: The Trump administration introduced its plan to roll back Obama-era standards that had the objective of cutting planet-warming emissions and raising fuel efficiency in cars and trucks sold in the U.S, according to CNBC. The administration will also seek to take away California's special authority to set its own fuel economy levels for autos, heightening a legal battle with more than a dozen states. The last plan required automakers to steadily increase fuel efficiency levels through 2025, while the new plan would freeze those levels in 2020. Publicly traded companies in the space include Daimler AG (DDAIF), Fiat Chrysler (FCAU), Ford (F), General Motors (GM), Honda (HMC), Nissan (NSANY), Toyota (TM) and Volkswagen (VLKAY).

3. AUTO TARIFFS: Meanwhile, Canada, the European Union, Japan, Mexico and South Korea are expected to meet in Switzerland to plot a response to threats by President Donald Trump to establish tariffs on U.S. imports of automobiles and car parts, according to Reuters, citing officials familiar with the talks. The Trump administration has considered tariffs up to 25%, despite warnings of cost hikes and a negative impact on the global auto industry.

4. U.S. ELECTIONS: Senior executives of Facebook (FB), Twitter (TWTR) and Alphabet's (GOOG; GOOGL) Google will testify to the U.S. Senate Intelligence Committee on September 5, according to Reuters, citing Senator Mark Warner, the committee's Democratic vice chairman. "We will be hosting senior executives to hear the plans they have in place, to press them to do more, and to work together to address this challenge," Warner said at a hearing looking into foreign efforts to influence U.S. elections. On July 31, Facebook said in a social media post that it had removed 32 Pages and accounts from Facebook and Instagram because they were involved in "coordinated inauthentic behavior" that is not allowed "because we don't want people or organizations creating networks of accounts to mislead others about who they are, or what they're doing." The company added that it is "clear that whoever set up these accounts went to much greater lengths to obscure their true identities than the Russian-based Internet Research Agency has in the past," which it supposes could be partly due to changes the company has made over the last year to make this kind of abuse harder.
