Rand Paul’s 2016 presidential campaign is mainly remembered for two news moments in 2015–2016: his launch and his eventual suspension/dropout early in the election season.
Campaign launch (April 2015)
Rand Paul officially announced his bid for the 2016 Republican presidential nomination on April 7, 2015, positioning the campaign as an effort to “take our country back,” and outlining an early push through early nominating states such as New Hampshire, South Carolina, Iowa, and Nevada.[1][6]
Suspension/dropout (February 2016)
On February 2, 2016, Paul suspended his 2016 presidential campaign after failing to gain sufficient support nationally and following disappointments in the early states (including Iowa), telling supporters he was ending the presidential run while continuing his political work in the Senate.[3][5]
If you want, tell me whether you mean U.S. news coverage (major outlets like ABC/CBS) or UK-based coverage as well, and I can summarize the most notable headlines and themes from that coverage specifically.
