Here are five things you must know for Wednesday, Aug. 22:

1. -- Stock Futures Slip Amid Trump Legal Drama

U.S. stock futures traded mixed on Wednesday, Aug. 22, ahead of two days of trade talks between the U.S. and China and as investors digested the latest legal fallout surrounding Donald Trump.

Contracts tied to the Dow Jones Industrial Average I:DJI   rose 2 points, futures for the S&P 500 I:GSPC  were down 0.75 points, and Nasdaq I:IXIC futures rose 6.25 points.

The S&P 500 set an intraday record high on Tuesday, Aug. 21, and closed with its fourth day of gains, setting up U.S. stocks to record their longest bull market run in history.

China and the U.S. will return to trade talks on Wednesday but expectations are low that the mid-level discussions will yield any progress.

Meanwhile, Trump's former personal attorney, Michael Cohen, pleaded guilty on Tuesday to campaign-finance violations and other charges, saying Trump directed him to arrange the payment of hush money to porn star Stormy Daniels and a former Playboy model to fend off damage to his White House bid.

Also on Tuesday, Paul Manafort, former chairman of Trump's presidential campaign, was found guilty on eight counts of bank and tax fraud.

The legal developments surrounding Trump have "taken the shine off the positive stock market story," said David Madden, a market analyst at CMC Markets UK.

2. -- Stocks Set for Longest Bull Market in U.S. History

The S&P 500 was poised Wednesday for the longest bull market in U.S. history.

According to the brokerage firm LPL Research, the current bull market started on March 9, 2009, in the wake of the financial crisis. According to CNBC.com, the bull market will turn 3,453 days old on Wednesday, eclipsing the previous record set in the 1990s, which ended with the dot-com bust.

Wall Street analysts have said there's no apparent reason it can't run further. The Federal Reserve's rate increases since 2015 are moving too gradually to hold it back, wrote TheStreet's Bradley Keoun.

The Fed on Wednesday will release minutes from its last meeting on July 31-Aug. 1. While the central bank didn't boost interest rates at that meeting, it has done so twice this year and economists expect the Fed to raise rates at its September meeting after consumer price inflation hit 2.9% in July, the highest level in six years.

The Fed minutes will be released at 2 p.m. ET. The economic calendar in the U.S. on Wednesday also includes Existing Home Sales for July at 10 a.m. ET, and Oil Inventories for the week ended Aug. 17, at 10:30 a.m..

3. -- Target, Lowe's Report Earnings

Second-quarter earnings at Lowe's Cos. (LOW) - Get Report  topped analysts' estimates but a same-store sales increase of 5.2% came in slightly below expectations. The home-improvement retailer also said it would close its Orchard Supply Hardware division.

Lowe's said it expects full-year same-store sales up 3%, and earnings of $4.50 to $4.60 a share. The stock fell 2.9% in premarket trading.

Target Corp. (TGT) - Get Report  posted second-quarter adjusted earnings of $1.47 a share, 7 cents ahead of estimates and same-store sales of 6.5% easily came in ahead of forecasts.

The retailer also raised its outlook for 2018 adjusted earnings and the stock jumped 5.6% in premarket trading.

4. -- Uber Hires a Chief Financial Officer

Uber Technologies Inc. named Nelson Chai as Chief Financial Officer, seemingly putting the ride-sharing company one step closer to holding an initial public offering.

CEO Dara Khosrowshahi didn't look to Silicon Valley to fill the role that had been vacant for three years, but to the world of insurance and warranty. Chai was most recently CEO of TPG Capital-backed The Warranty Group before the Chicago company's $2.5 billion sale to Assurant Inc.

5. -- Zynga Strikes Deal for 'Star Wars' Game With Disney

Zynga Inc. (ZNGA) - Get Report shares jumped 12% in premarket trading on Wednesday after the video game maker said it struck a multiyear deal with Walt Disney Co. (DIS) - Get Report to develop a "Star Wars" mobile game.

New "Star Wars" titles will be managed by Zynga's NaturalMotion studio, which is based out of the U.K.
