The Dow and the S&P 500 ended nearly flat on Tuesday, while the Nasdaq posted its gain for a third consecutive session, influenced by recent political events. Initially, the broader markets moved lower following disclosure of emails by Donald Trump Jr. containing "high level and sensitive information" regarding Hillary Clinton that would aid the Trump presidential campaign. However, broader markets recovered as Senate Republican leader Mitch McConnell announced delay in the start of Senate’s summer recess, providing lawmakers additional time to progress on the new health care law. Additionally, energy shares moved north due to uptick in oil prices as Energy Information Administration (EIA) lowered its projection for U.S. output.For a look at the issues currently facing the markets, make sure to read today’s Ahead of Wall Street article.The Dow Jones Industrial Average (DJI) advanced marginally by 0.55 points to close at 21,409.07.

Initially, broader markets had dropped following the disclosure of a series of emails by Donald Trump Jr. that were exchanged with Rob Goldstone, who has connections with President Donald Trump.The emails offered Trump Jr. "high level and sensitive information" from the Russian Government that would implicate Hillary Clinton, a move intended to support Trump’s presidential campaign. The exchange of emails was reported to have taken place before Trump Jr. met with Russian attorney Natalia Veselnitskaya on June 9, 2016. Speaking to NBC news, Veselnitskaya however ruled out the fact that she had any association with the Kremlin. The meeting is important as Robert Mueller, a special counsel and congressional committees are probing whether the Trump campaign had any connection with the Kremlin. This development raised concerns that the controversy related to Russian interference in Trump’s presidential campaign would worsen.Delay in Senate’s Summer RecessMeanwhile, broader markets recovered from its initial losses after Senate majority Leader Mitch McConnell declared delay in the start of Senate’s summer recess. McConnell delayed Senate’s summer recess till third week of August providing lawmakers extra time to progress on major legislative issues including health care Bill. This delay raised prospects for the passage of the new health care law that is crucial toward implementing Trump’s other pro-growth agendas including tax reforms. This in turn helped the broader markets to pare initial losses.Energy Shares GainOil prices continued to move north on Tuesday, following the release of a report by the EIA. The government agency lowered its 2018 U.S. output projection by 1% to 9.90 million barrels per day. Moreover, speculation about a possible production cut from Libya and Nigeria boosted oil prices. The increase in oil prices had a positive impact on the energy shares. WTI crude prices advanced by $0.64, or 1.4%, to $45.04 a barrel.
