Passage: Gillekens made his debut for OH Leuven in the 2014–15 Belgian Cup in the sixth round match against Kortrijk, a 1-3 loss, although that season he was part of the reserves and only fourth goalkeeper behind Logan Bailly, Yves Lenaerts and Senne Vits. Later that season he also played one match in the 2014–15 Belgian Second Division against Mons. Although Gillekens was promoted to third keeper for the 2015–16 season, he did not play a single match that season. Following the relegation from the 2015–16 Belgian Pro League, first goalkeeper Rudy Riou was released while second goalkeeper Yves Lenaerts had already signed for ASV Geel. As such, Gillekens was promoted to first goalkeeper for the 2016–17 season in the Belgian First Division B. During the winter 2017–18 transfer window OH Leuven signed Kawin Thamsatchanan, captain of the Thailand national football team and soon thereafter Gillekens was demoted to reserve goalkeeper. Following Thamsatchanan's injury during the 2018–19 season, Gillekens again became first goalkeeper for a few matches before then being surpassed by Laurent Henkinet. Towards the end of the season, Gillekens was even demoted to third goalkeeper with Thamsatchanan now taking his place on the bench and after the final match of the season it became clear that Gillekens would not be signing a new deal at OH Leuven.

Passage: The station became WQXL in 1962 after the station was sold to the Belk Broadcasting Company. The WOIC call sign resurfaced that same year on 1320 AM (now WISW). WQXL originally aired a Big Band format, which eventually gave way to a Top 40 format by the end of the decade. However it was handicapped with a daytime-only signal and was unsuccessful in competing against format rivals 1230 WNOK and 1400 WCOS, which each had full-time signals. Probably its most notable personality was Mackie "Cactus" Quave who had worked at 560 WIS (now WVOC) and had a successful kids TV show on NBC Network affiliate Channel 10 WIS-TV. WQXL switched to country music in the summer of 1966, but again was bested by rival 620 WCAY (now WGCV). In 1973, the station switched to religious programming and eventually adopted a Contemporary Christian format.
 Link Information: WCAY 620 signed on August 22, 1958  Question: How many years had the station been on air when it switched its call sign to WGVC?

Passage: A July 25, 2019 telephone call between Trump and Ukraine president Volodymyr Zelensky led in September to a whistleblower complaint and an impeachment inquiry against Trump. Two weeks after the inquiry was launched, Trump claimed in a conference call with Congressional Republican leaders that he had only made the telephone call at Perry's urging. Perry's spokesperson said that Perry had suggested Trump discuss energy security with Zelensky, but energy was not mentioned in the publicly released memo about the conversations, which instead focused on Trump asking Zelensky to launch investigations into Joe Biden, Hunter Biden, Crowdstrike, and the 2016 U.S. presidential election. Per Trump's direction earlier this year, Perry spoke with Rudy Giuliani about Ukraine, which Mick Mulvaney confirmed. Perry denied ever mentioning the Bidens in his discussions with Trump or Ukrainian officials. Mulvaney had put Gordon Sondland, Kurt Volker, and Perry in charge of managing the Ukraine–United States relations instead of diplomats at the National Security Council and the US Department of State.
