Example Input: Justice Department special counsel Robert Mueller broke his own record this week for guilty pleas. On Tuesday  Dutch attorney Alex van der Zwaan appeared in federal court and admitted he had lied to investigators about his contacts with  Donald Trump's former campaign vice chairman  Rick Gates .
On Friday   Gates himself  appeared before a federal judge and confirmed that  he  is changing  his  plea to guilty.  He  had been fighting the case brought against  him  and the former Trump campaign chairman  Paul Manafort  which alleged they laundered millions of dollars and broke other laws related to their work for clients in Ukraine.
 Gates  and Manafort have not been charged with conspiracy to defraud the U.S. by "impairing  obstructing and defeating the lawful functions of the government through fraud and deceit for the purpose of interfering with the U.S. political and electoral processes." That was the charge Mueller leveled at 13 Russians and three Russian companies he says did interfere with the election.
Or the special counsel's office could be laying down one brick in a larger structure. At the very least   Gates'  future testimony against  his  longtime business partner raises the likelihood that Manafort could be convicted of some or all of the charges  he  continues fighting.
Manafort and his lawyers know this. So one of Mueller's strategies in getting  Gates  to turn state's evidence might be to persuade Manafort to do the same and tell what he knows about other people in the Trump campaign orbit.
Or evidence from  Gates  might be what the special counsel's office needs to build a case against Manafort for conspiring in the 2016 Russian interference effort. Or  after years of working with Manafort   Gates  might have other evidence that would permit Mueller to bring new charges against Manafort.
Mueller announced a new indictment in Manafort's case on Friday evening. After  Gates  appeared in federal court Friday to enter his plea  Manafort continued to maintain his innocence and said he remained committed "to defend myself against the untrue piled up charges contained in the indictments against me."

Example Input: Madrid (AFP) â Real Madrid quietened crisis talk after back-to-back defeats as  Marco Asensio  added to  his  collection of wonder strikes in a 3-0 victory over Las Palmas at the Santiago Bernabeu on Sunday.
A booking would have ruled Casemiro out of the Madrid derby against Atletico in two weeksâ time and he was quickly replaced after  Asensio  secured the three points in stunning fashion.
 Asensio  has made a habit of netting in spectacular fashion in  his  first 18 months at Madrid and pounced on a loose ball 30 yards from goal to rifle a shot that rose all the way on its trajectory into the top corner.
Ronaldo fired inches over twice more  but  whilst his luck remained out in front of goal   he  did provide an enticing cross from which Isco slotted home at the back post for Madridâs third.
Example Output: Marco Asensio

Example Input: Federal Reserve Chairman Ben Bernanke on Monday said the central bank will keep a close eye on the sliding U.S. dollar even as he pledged anew to keep interest rates at record-lows to nurture the economic recovery.
dollar
 In remarks to the Economic Club of New York  Bernanke engaged in a delicate dance.
 He made clear Fed policymakers will keep rates at super-low levels. Yet through his words  Bernanke is also trying to bolster confidence in the dollar without actually raising rates  a move that could short-circuit the fragile recovery.
 "We are attentive to the implications of changes in the value of the dollar " Bernanke said in rare remarks about the greenback. The Fed  he said  will continue to "monitor these developments closely."
 Although commodity prices -- such as oil -- have risen lately  that pickup likely reflects a revival in global economic activity and the recent depreciation of the dollar  Bernanke said. Even so  the Fed chief predicted inflation probably will remain "subdued for some time."
 That gives the Fed leeway to hold rates at record-low levels for an "extended period " he said  repeating a pledge made at the Fed's meeting earlier this month.
 Bernanke predicted the U.S. economy should continue to grow next year  but he warned of "important headwinds" that will restrain the recovery  including a weak job market and tight credit for small businesses and households.
 Those forces "likely will prevent the expansion from being as robust as we would hope " he said.
 Bernanke said the rebound reflected more than "purely temporary factors" and predicted growth would continue into next year.
 But he cautioned there is uncertainty about how the economy will evolve next year  and warned that "future setbacks are possible."
 Bernanke said the unemployment rate "likely will decline only slowly" if economic growth remains "moderate" as he expects.
 Because jobs are likely to remain scarce for some time  consumers -- critical shapers of overall economic activity -- will be cautious about spending  Bernanke said.
 Banks dealing with the fallout from soured commercial real estate loans also could slow progress on efforts to get credit flowing more freely again  the Fed chief said. And credit difficulties will limit the ability of some businesses to expand and hire.
 "Overall a number of factors suggest that employment gains may be modest during the early stages of the expansion " Bernanke said.
