Example Input: (CNN) The President has excoriated football players who have joined a protest movement by former 49ers quarterback Colin Kaepernick as unpatriotic. But the President is overlooking history -- which shows athletes now lauded as heroes  like  Jackie Robinson and Muhammad Ali   raising  their  voices (or taking a seat) in protests similar to Kaepernick's.
 Jackie Robinson   rightfully celebrated for showing enormous grace under pressure while breaking baseball's color line  refused to stand for the National Anthem after  his  playing days.
Jackie Robinson as a Brooklyn Dodger.
As  he  described in  his  1972 autobiography   Robinson -- like contemporary NFL players --  was protesting against institutional racism.  He  was expressing  his  feelings of alienation from America's system of racial apartheid.
 Robinson 's pugnacious brand of civil rights activism set the stage for succeeding generations of black athletes. Eleven-time NBA champion Bill Russell emerged as one of the most outspoken civil rights advocates of the 1960s  at a time when the city he played in  Boston  represented one of the most racially segregated cities in the North.
Above all  black American athletes are citizens  fathers  brothers  husbands and sons who have a right and responsibility to continue a long struggle for dignity exemplified by Jackie Robinson  Bill Russell and many others.

Example Input: JERUSALEM (Reuters)  - Israeli chip maker Mellanox Technologies  saw  its  shares surge on the Nasdaq on Tuesday after activist hedge fund Starboard Value LP bought a 10.7 percent stake to influence strategy.

Starboard became the biggest shareholder in Mellanox after disclosing its stake purchase - valued at around $300 million - and said the chipmaker could improve its financial performance.
In particular  Starboard is concerned that Mellanox  which makes computer networking products using InfiniBand and Ethernet technology  rejected a potential merger with rival Marvell Technology. Starboard  in its filing  said Marvell had expressed interest in discussing a “potential strategic transaction” but  Mellanox  declined to enter into talks.
 Mellanox’s  shares opened 14 percent higher and were still up 11 percent at $56.65 by 1552 GMT.  They  had risen 25 percent this year through Monday  underperforming Marvell’s 56 percent rally and a 48 percent increase in the Philadelphia Semiconductor index.
The source noted that  Starboard - which believes Mellanox is spending too much on research and development and other corporate expenses to try to boost revenue  sacrificing margins compared with peers - must stop disappointing investors .
“ They  need to improve financial performance or sell the company. Either way it is to see the stock price go up significantly ” the source said  noting there was a “long list of potential buyers” for Mellanox.
 Mellanox  which was founded in 1999 and has a market value of nearly $3 billion   said in a statement on Tuesday that  it  “welcomes the input and investment” from all  its  shareholders.
“In line with our commitment to drive enhanced shareholder value  the Mellanox board of directors and management team continually review our operational and strategic priorities and are committed to acting in the best interests of our shareholders ” it said.
Barclays analyst Joseph Wolf  who downgraded  Mellanox  to “underweight” after  its  earnings report  said that while there is room for  Mellanox  to cut expenses   its  growth stems from accelerating revenue during product transitions.
