The report stated that Trump withheld military aid and a White House invitation in order to influence Ukraine to announce investigations into Trump's political rivals.

During The Game Awards 2019, Microsoft officially unveiled Xbox Series X—a new Xbox model to be released in late-2020. The console is estimated to be four times as powerful as Xbox One X, with support for 8K resolution, real-time ray-tracing, and 120 frames-per-second renderings. Xbox Series X is stated to be backward compatible with all games and accessories currently compatible with Xbox One (including original Xbox and Xbox 360 titles that are supported on Xbox One). In addition, there are no immediate plans for first-party games to be exclusive to the new console over the Xbox One. Following the unveiling, a Microsoft spokesperson stated that Xbox Series X constituted an entry in a fourth generation of Xbox hardware, which will be branded simply as "Xbox" with no subtitle. Prior to the E3 reveal, it had been speculated that Microsoft was developing two next-generation Xbox consoles codenamed "Anaconda" and "Lockhart", which were high-end and low-end models respectively. Microsoft has focused solely on a high-end product in its current marketing.
